Wilshire Grand’s Continuous Concrete Pour May Break World Record

Los Angeles, United States – 11 February 2014

Construction of the supertall 335-meter Wilshire Grand Tower in Los Angeles is underway, with plans to fill a 30-meter foundation with concrete in one fell swoop on February 15.

Building Architect Chris Martin, of A.C. Martin Partners, said “The project will attempt to set a Guinness World Record with the largest continuous pour ever.”

Concrete trucks containing 2,100 loads will deliver 1,800 cubic meters of concrete will parade to the site, accompanied by a marching band and local dignitaries for the grand pour.

“Pouring the massive amount of concrete at once allows workers to save several weeks’ time over a more normal, slower pour and will yield one solid, connected foundation rather than requiring mechanical connections between sections,” said Martin.

To prevent cracks caused from overheating, 19 miles of refrigeration piping will cool the steel reinforcements along the foundation.

When complete, the Hanjin Group-developed tower will rise to become projected tallest building west of the Mississippi River.

Los Angeles Mayor’s Call to Action to Seismically Strengthen City!

Mayor Garcetti announces his earthquake plan on Monday. SEAOSC President Kevin O’Connell on far right.

As practicing engineers we are charged by our licensing rules and the building code"to safeguard life, health, property, and public welfare". However, in our daily efforts we often focus stringently on the safeguarding of life through code-based "life-safety" standards, while letting the other charges of protecting property and public welfare settle into our subconscious as after thoughts of the first.

Monday’s announcement by Mayor Garcetti in Los Angeles, could be seen as a call to our SEAOSC membership to provide our engineering expertise beyond the building footprint and into the domain ofprotecting the public welfare of greater Los Angeles. As the Mayor states, "the known risks – to life, property and our overall economy – are too great", for us to limit our solutions to a single building project. Instead we should prepare ourselves to participate in a growing dialogue which recognizes that single buildings, standing alone, do not make a city.

As many of you may know, SEAOSC is actively participating in the

conversations led by Dr. Jones regarding building earthquake performance. We will continue to engage and support the decision making process as this moves from mayoral initiative to effective City policy. The linked articles will help you get up to speed with where the process stands today. Over the coming weeks and next few months we will keep you informed of additional developments as they unfold. We encourage you to attend the January 7th SEAOSC Dinner meeting, "Resilience By Design: The City of Los Angeles Plan to Reduce Seismic Vulnerability" which will be on the current status of City of LA Ordinances.

SEAOSC’s participation in activities such as this provides a clear example of how the association endeavors to add value to your membership by enhancing the profession of Structural Engineering in the State of California and providing a portal for the public to find structural engineers. But don’t forget, your Association is only as strong as the participation of its membership…so, check back with us often for more info, updates, and ways to get involved to support this and other important activities.

Sincerely, Kevin O’Connell, SEAOSC President
& all of the SEAOSC Board of Directors



CTBUH News: One World Trade Center is Now the World’s Third-Tall est Building

CTBUH Commemorates One World Trade Center
With Updated “World’s 20 Tallest Buildings” Poster
The 541-meter (1,776-foot) One World Trade Center has now become the world’s third-tallest building, according to the height criteria set by the Council on Tall Buildings and Urban Habitat (CTBUH). One World Trade Center now ranks only behind the Burj Khalifa in Dubai, UAE (828 meters) and the Makkah Royal Clock Tower in Mecca, Saudi Arabia (601 meters) in the tallest building stakes. The office building at the center of the massive rebuilt World Trade Center in Lower Manhattan, New York, opened its doors Nov. 3 to an anchor tenant, media company Condé Nast.

To reflect this historic moment, the CTBUH has updated its “World’s 20 Tallest Buildings” Poster, which is now available for purchase at the CTBUH Web Shop.

One World Trade Center is a highly anticipated project that began construction in 2005 and has been the focus of much media attention and celebration of its achievement as a symbol of resilience. In late 2013, the building became the subject of massive global media interest when the CTBUH confirmed that the tower would become “The Tallest in North America” upon completion, which has now been achieved. CTBUH criteria defines “completed” as “topped out architecturally and open for business, or at least partially occupied." One World Trade Center also now ranks as the World’s Tallest All-Office Building.

Douglas Durst, Chairman of the One World Trade Center’s developer, The Durst Organization, received the CTBUH 2014 Lynn S. Beedle Lifetime Achievement Award last week in Chicago (see here). Mr. Durst also took the opportunity to confirm that the Durst Organization would host a networking reception at the top of One World Trade Center on the occasion of the CTBUH 2015 New York Conference, which will take place in October 2015 on the theme of “Global Interchanges: Resurgence of the Skyscraper City.”

The CTBUH maintains data and criteria on the heights of tall buildings worldwide and is the recognized authority behind the “World’s Tallest Building” designation.

CTBUH Names One Central Park
“Best Tall Building Worldwide” for 2014

Awards Ceremony Also Honors Douglas Durst and Peter Irwin for Lifetime’s Work
November 6, 2014
See all the Winners and Finalists
The Council on Tall Buildings and Urban Habitat (CTBUH) awarded One Central Park, Sydney, Australia, the title of “Best Tall Building Worldwide” at the 13th Annual CTBUH Awards Ceremony and Dinner. As part of a nearly year-long juried selection process across 88 entries, the Awards Jury first selected a Best Tall Building in four regions: the Americas, Middle East and Africa, Europe and Asia & Australasia. Senior representatives of each of these four winners then gave a presentation at the CTBUH Awards Symposium Nov. 6 at the Illinois Institute of Technology, Chicago, with the Jury convening immediately afterwards. The winner was announced at the Awards Dinner following the Symposium.

One Central Park, Winner of the Best Tall Building Worldwide
“Every member of the team challenged us to deliver something that was out of the box,” said Michael Goldrick, Project Management Director, Frasers Property, who had presented on the project earlier. “The Ateliers Jean Nouvel team put together challenges we never really envisioned. It really drove us to deliver what I think for Sydney and Australia is a really iconic building.”

“Seeing this project for the first time stopped me dead,” said juror Antony Wood, Executive Director, CTBUH. “There have been major advances in the incorporation of greenery in high-rise buildings over the past few years – but nothing on the scale of this building has been attempted or achieved. One Central Park strongly points the way forward, not only for an essential naturalization of our built environment, but for a new aesthetic for our cities – an aesthetic entirely appropriate to the environmental challenges of our age.”

From left to right: Wiel Arets, Illinois Institute of Technology; Bertram Beissel, Ateliers Jean Nouvel; Michael Goldrick, Frasers Property; Toru Abe, Sekisui House Australia Pty Ltd; and Robert Bird, Robert Bird Group
“This project was about the visibility of sustainable design,” said Bertram Beissel, Partner, Ateliers Jean Nouvel, during the winning project presentation. “If we do all these sustainable things and no one can see them, do they really exist? The choices we make for a sustainable future cannot be made in the future. They must be made today.”

The audience vote, taken separately, submitted via text message, and kept from the jury’s view until after their verdict had been announced, was also for One Central Park.

Over 500 delegates attended the daytime Awards Symposium featuring presentations by all the winners and featured finalists
Lynn S. Beedle Lifetime Achievement Awardee Douglas Durst’s is a member of the third generation to lead The Durst Organization, which was founded in 1915 and is one of New York’s oldest and most respected privately held owner-builder-managers of commercial and residential real estate. Since 1968, Durst has shown leadership by making pioneering investments in energy-saving retrofits, and in new-build sustainable skyscrapers, such as One Bryant Park and 4 Times Square (Conde Nast Building).

Peter Irwin, RWDI, winner of the Fazlur R. Khan Lifetime Achievement Medal, has led wind engineering on many of the world’s tallest buildings, including the Petronas Towers, Taipei 101, Burj Khalifa, the Trump International Hotel & Tower, and Shanghai Tower. His Irwin Sensor, developed for wind tunnel studies of pedestrian impact, is now widely used at many laboratories around the world, and his work has ensured the safe and stable construction and operation of tall buildings worldwide.

The Interlace, winner of the inaugural Urban Habitat Award, is a 1,040-unit apartment complex consisting of 31 apartment blocks, each six stories tall and 70 meters long, stacked in hexagonal arrangements around eight large-scale, permeable courtyards. The stacking of the volumes creates a topographical phenomenon more reminiscent of a landscape than of a typical building. An extensive network of communal gardens and spaces is interwoven with amenities, providing multiple opportunities for social interaction, leisure and recreation – both on the roofs of, and in between, these stacked horizontal blocks.

The International Commerce Centre (ICC), a 484-meter office tower in Hong Kong, has won the inaugural Performance Award. Information collection and sharing is one of the key reasons ICC is this year’s winner. Completed in 2010, the ICC is Hong Kong’s tallest building, but is being recognized for its management team’s devotion to managing the facility from a commercial, environmental and community standpoint. ICC’s energy performance in 2013 placed it among the top 90th percentile of energy-efficient tall commercial buildings. The ICC arrived at this milestone through the combination of a computerized building management system, a policy of replacing underperforming mechanical equipment, and perhaps most importantly, incorporating measurement and reporting into its high-service business model. Each tenant is assigned its own account manager, who provides responsive service, but also encourages tenants to participate in, and undertake their own, energy-saving initiatives. As an economic / commercial validation of this approach, the building is 98 percent occupied.

BioSkin, a system of water-filled ceramic pipes that cools the exterior surface of buildings and their surrounding micro-climates as used at the NBF Osaki Building in Tokyo, Japan, is the Innovation Award Winner. Based on the traditional Japanese practice of uchimizu, the sprinkling of water to lower ambient temperatures, clean the streets and keep dust at bay, BioSkin absorbs heat through rainwater evaporation through a fine filigree of porous tubes, mitigating the urban heat island effect by cooling the building as well as its immediate surroundings. Through this process, the surface temperature of the building enclosure can be reduced by as much as 12°C, and its micro-climate by about 2°C. The potential implications of this are substantial: If a large number of buildings in a city used such a system, ambient air temperature could be reduced to the point that cooling loads for many buildings, even those without the system installed, could be reduced.

Innovation Award Winner: BioSkin, first used on NBF Osaki Building The team from BioSkin, led by Tomohiko Yamanashi, Nikken Sekkei (center), accepts their award from Awards Jury Chair Jeanne Gang, Studio Gang Architects (left)
Post Tower, a 163-meter office tower in Bonn, Germany, received the 10 Year Award. Completed in 2002, the Post Tower blazed new trails by using technically integrated design to deliver high performance. Its two elliptical volumes, with an atrium between, work together with site and wind orientation, a double-skin, operable façade, and stack ventilation to remove much of the need for mechanical ventilation commonly found in large buildings. This not only allows the building to consume only 75 kilowatt-hours per square meter per year, which is 79 percent less energy than a typical office building of its size; it also makes for pleasant interior sky garden spaces and a more efficient floor plate.

The Edith Green-Wendell Wyatt (EGWW) Federal Building, winner of the Best Tall Buildings Americas award, was an existing 18-story, 512,474 square-foot (47,610 square-meter) office tower, completed in 1974. The building no longer met the functional or the energy and conservation requirements of the contemporary US government, so a major renovation project was undertaken. A mechanical upgrade was paired with a full replacement of the building envelope with a distinctive shading facade, affording better energy performance and a new lease on life.

This project achieves operational sustainability that would be admirable in a brand-new building, let alone a retrofit of a 1970s “energy hog.” The building has been transformed from a bunker-like, concrete-encased mass into a trellised volume that seems more lightweight by an order of magnitude, yet affords more floor space than the previous version. The transformation speaks volumes about the change in attitude of Americans toward their environment, and in the relationship between Americans and their government.

“Improving energy performance is an obligation of the building community, and it’s great to see the government meaningfully participating in that objective,” said Jeanne Gang, awards jury chair and founding principal of Studio Gang Architects. “This renovation project significantly expands the original design’s energy strategies, while, at street level, contributing to a more active urban experience.”

De Rotterdam, winner of the Best Tall Building Europe award, is the largest building in the Netherlands, at 150 meters’ height and 162,000 square meters of area. Its mass is broken down by three interconnected mixed-use towers, accommodating offices, apartments, a hotel, conference facilities, shops, restaurants, and cafes.

De Rotterdam is an exercise in formal interpretation that is at once reminiscent of an imported mid-century American skyscraper, but epitomizes the off-center experimentalism of modern Dutch art of the foregoing century. The nighttime twinkling of the lights indicating different programs throughout the day lends dynamism and contributes to the humanization of the monoliths. It is as if the moai of Easter Island were constantly craning their necks and raising their eyebrows at the change all around.

“This three-tower set acknowledges its inevitability on the skyline, breaking down what could have been an overwhelming mass into digestible parts,” said juror Saskia Sassen, Robert S. Lynd Professor of Sociology and Co-Chair, The Committee on Global Thought, Columbia University. “It demonstrates a confident agility as one shifts perspective and the sun circumscribes it.”

Cayan Tower, winner of the Best Tall Building Middle East & Africa award, is a 75-story luxury apartment building with a striking helical shape, turning 90 degrees over the course of its 304-meter height. Each floor is identical in plan, but is set 1.2 degrees clockwise from the floor below, giving the tower a distinctive form by way of an innovative, efficient, repeatable structure.

In an environment where so many tall buildings lined up in a row against a humid and reflective backdrop can make massive buildings seem like cardboard matte cutouts, it takes an extraordinary design gesture to indelibly express the three-dimensionality of a building. Cayan Tower makes that gesture; happening upon its dancing form in the skyline is like encountering a hula-hooper on a train full of gray flannel suits.

“The intelligent helical design of the Cayan Tower responds to very specific and challenging local conditions, whilst providing a visually striking new landmark for the Dubai skyline,” said juror Sir Terry Farrell, Principal, Farrells. “This building expresses its structure through its form in an elegant and sophisticated way, enhancing the architecture of the existing waterfront site.”

Seismic Evaluation and Retrofit of Existing Buildings (41-13)

Here is a good resource.

Sponsored by the Structural Engineering Institute of ASCE.

Seismic Evaluation and Retrofit of Existing Buildings describes deficiency-based and systematic procedures that use performance-based principles to evaluate and retrofit existing buildings to withstand the effects of earthquakes. This next-generation standard combines the evaluation and retrofit process and puts forth a three-tiered process for seismic evaluation according to a range of building performance levels—from collapse prevention to operational—that marry targeted structural performance with the performance of nonstructural elements. The deficiency-based procedures allow the evaluation and retrofit effort to focus on specific potential deficiencies deemed, on the basis of past earthquake observations, to be of concern for a permissible set of building types and heights. The systematic procedure, applicable to any building, sets forth a methodology to evaluate the entire building in a rigorous manner.

Analysis procedures and acceptance criteria are established and requirements put forth for foundations and geologic site hazards; components made of steel, concrete, masonry, wood, and cold-formed steel; architectural mechanical and electrical components and systems; and seismic isolation and energy dissipation systems. In addition, screening checklists are provided for a variety of building types and seismicity levels in support of the Tier 1 process.

This standard updates and replaces the previous Standard ASCE/SEI 41-06, Seismic Rehabilitation of Existing Buildings, as well as Standard ASCE/SEI 31-03, Seismic Evaluation of Existing Buildings.

Standard ASCE/SEI 41-13 serves structural engineers, design professionals, code officials, and building owners interested in improving the seismic performance of existing buildings.

INSTRUCTOR: Fred Turner, PE, SECB

Sponsored by ASCE’s Structural Engineering Institute and ASCE Continuing Education.

The evaluation and retrofit of buildings with unreinforced masonry (URM) brick bearing walls is a significant part of the ongoing effort to improve the existing structures in areas subject to earthquake hazard. This webinar introduces the requirements of Chapters 11 – Masonry, 13 – Architectural, 15 – System-Specific Performance Procedures, and 16 – Evaluation Checklists of ASCE 41-13 “Seismic Evaluation and Retrofit of Existing Buildings†for URM brick bearing wall buildings. The new standard provides a unified method for evaluating and retrofitting existing buildings for earthquakes and eliminates significant inconsistencies between the two previous standards.

Purpose and Background

URM brick bearing wall buildings are consistently one of the most vulnerable building types and are common candidates for seismic evaluations and retrofits. Performance of previously retrofitted URM buildings has been mixed, but thorough retrofits with effective enforcement and quality assurance can significantly reduce the risks of collapse and falling components. This webinar will familiarize participants with common considerations including documenting the conditions of unreinforced masonry bearing walls, options for analysis, and design of enhancements.

INSTRUCTOR:
Jon D. Raggett, Ph.D., P.E., S.E., M.ASCE

Excellent presentation. The instructor was knowledgeable and kept our attention throughout; never dull or boring. This is the best ASCE seminar I have attended. William Bretnall, Madsen Kneppers & Associates, Ft Lauderdale, FL

Purpose and Background

Hurricanes Andrew (1992), Iniki (1992), Hugo (1989), four hurricanes of 2004, hurricanes Katrina, Rita and Wilma of 2005 and the Kansas-Oklahoma tornado outbreaks (1999 & 2003) were catastrophic demonstrations of the increasing vulnerability of buildings and other structures (tanks, signs, towers, etc.) to severe wind storms. Wind induced property losses now annually exceed the sum of all other losses from natural hazards.

This seminar addresses wind effects, provides guidelines for assessing design wind loads for buildings and other structures, and offers a discussion of the advantages of wind tunnel testing. This seminar is based on the ASCE publications Minimum Design Loads for Buildings and Other Structures (ASCE 7-10) and Significant Changes to the Wind Provisions of ASCE 7-10. While much of the instruction focuses on assessing wind loads, a portion of the seminar is directed to review wind damage experience of the past thirty years and lessons learned from the experience. Discussion in the seminar will focus on the new ASCE 7-10 Standard.

DAY ONE of this seminar is devoted to a comprehensive review of basic wind engineering fundamentals and the background of the wind load provisions of the national standard, ASCE 7- 10.

DAY TWO focuses on the application of national standard ASCE 7-10 with hands-on experience gained by working through a number of examples utilizing provisions of ASCE 7-10. A portion of the day includes going beyond the standards, with discussion of the determination of site specific wind speed, and wind tunnel testing.

Seminar Benefits

  • Get comprehensive guidelines for assessing wind loads to be used in the design of buildings and other structures
  • Review basic concepts of wind engineering (aerodynamics and structural dynamics)
  • Learn how to identify a wind design problem
  • Find out how wind damages buildings and ensure wind resistant construction
  • Learn about wind tunnel testing and the interpretation of results
  • Examine the provisions of ASCE 7-10
  • Learn how to review wind speed data
  • Use case studies to examine past performances of low, medium, and high-rise buildings in severe storms

Learning Outcomes

Upon completion of this seminar, you will be able to:

  • Understand the fundamentals of wind engineering
  • Use ASCE 7-10 to interpret and incorporate the fundamentals of wind engineering
  • Calculate wind loads on buildings and other structures

Assessment of Learning Outcomes

ATC-SEI Conference on Improving the Seismic Performance of Existing Buildings

On behalf of the Applied Technology Council (ATC) and the Structural Engineering Institute of the American Society of Civil Engineers (ASCE), we would like to invite you to join us in San Francisco on December 10-12, 2015 at the Hyatt Regency Hotel. Following the success of the 2009 conference, this state-of-the-industry forum continhome-bannerues the effort of improving the seismic performance of existing buildings and other structures.

The program is being planned to provide a forum for the presentation and exchange of new information on the seismic evaluation and seismic rehabilitation of existing buildings, including case studies, new discoveries, innovative use of new technologies and materials, implementation issues, needed improvements to existing standards and methods, and socio-economic issues. The goal is to provide an invaluable opportunity to advance the understanding of the tools, techniques, and innovations available to assist the attendees in meeting the challenges of seismic evaluation and rehabilitation.

NASCC: The Steel Conference Presents Special Seismic Sessions

This will be a great conference to go to. Bummed it is not in California.

Twenty years ago the Northridge Earthquake shook California and the results surprised designers throughout the U.S. AISC and the steel industry is presenting a special series of sessions at this year’s NASCC: The Steel Conference examining the lessons learned and the state-of-the-art in seismic design.

The special sessions kick off on Wednesday, March 26 with presentations on what happened in Northridge and the development of the SAC Steel Project, presented by FEMA Technical Advisor Mike Mahoney and the University of California at Berkeley’s Steve Mahin. Other presentations during the three day conference include:

  • The Moment Connection Details We Left Behind (and Why) — Mike Engelhardt, University of Texas at Austin
  • The Changes to Design Practice — Tom Sabol, Englekirk and Sabol
  • Revisiting W1a Indications — Duane Miller, The Lincoln Electric Company
  • Failure Analysis of Pre-Northridge Connections – Lessons Learned — John Barsom, Barsom Consulting
  • Japan’s Experience in Kobe — Masayoshi Makashima, Kyoto University
  • The Changes in Resulted in Research — Chia-Ming Uang, University of California at San Diego
  • AISC 341 Then and Now — Jim Malley, Degenkolb Associates
  • AISC 358: Prequalified Moment Connections — Ron Hamburger, Simpson, Gumpertz & Heger
  • The Changes in Materials and Inspection — Tom Schlafly, AISC
  • The Changes in Fabrication and Erection — Bob Hazleton, Herrick Corp.
  • Column Base and Splice Details — Amit Kanvinde, University of California, Davis
  • Conventional Braced Frames — Charles Roeder, University of Washington
  • Buckling-Restrained Braced Frames — Rafael Sabelli, Walter P Moore
  • Shear Walls — Michel Bruneau, State University of New York at Buffalo
  • Systems that Mix Steel and Concrete (Beyond Composite Design) — Jerry Hajjar, Northeastern University
  • System Reliability — Greg Deierlein, Stanford University
  • ASCE 41, John Hooper, Magnusson Klemencic Associates

In addition to the special seismic presentations, NASCC: The Steel Conference offers more than 100 technical sessions and 200 exhibition booths. The Steel Conference is widely recognized as the place for engineers, fabricators, detailers and erectors to learn about structural steel design and construction, to interact with their peers and to see the latest products for steel buildings and bridges. Each year more than 3,500 professionals gather. It’s a once-a-year opportunity to learn the latest techniques, see the most innovative products and network with your peers and clients. One low registration fee gains you admittance to all technical sessions (including NASCC: The Steel Conference, the Annual Stability Conference, the World Steel Bridge Symposium, the Technology in Steel Conference, and the T.R. Higgins Lecture.

The Steel Conference will be held March 26-28 in Toronto. For full information or to register, visit www.aisc.org/nascc. Registration is currently $330 but increases $10 each week until the conference.

I hope to see you in Toronto.

Los Angeles, California – the home of the coming seismic soft story failures

While UC Berkeley may have some data, this doesn’t mean its accurate. However, any information that can save lives is necessary. I am surprised that property owners aren’t smart enough to hire their own structural engineers.

How Canada is hoping to produce well-rounded Engineers

I think the California curriculum already does a good job at this. But then makes us Structural Engineers take courses that are completely ridiculous like Electrical Engineering – just to pass the FE. If they want us to be prepared for the FE exam with supplemental courses from other disciplines of engineering, the California Engineering colleges should put all of these FE prep-type courses into 1 course and save students several semesters of boredom.

Who needs the humanities? Engineers

Another supertall skyscraper presents an overturning structural engineering challenge.

Tall and skinny will require extra deep piles/caissons into the earth to accomodate the wind induced overturning moments at the foundation interface. This will be very costly and the square footage gained from a skinny platform at each level may not outweigh the costs of construction over a life-cycle economic analysis.
