Steel Shots: WTC Oculus Takes Shape
Posted by Tasha Weiss on November 8, 2013 at 5:37 PM.
Big steel is rising for the “Oculus” at the World Trade Center Transportation Hub, as shown in the above photo taken last week by AISC’s Mid-Atlantic Regional Engineer, Jacinda Collins. The structure, which frames the Transportation Hub’s main concourse, features a curved, wing-like appearance and uses more than 11,000 tons of structural steel to create its distinctive shape. Click on the photo to view a rendering of the project, courtesy of the Port Authority of New York and New Jersey.
The World Trade Center Transportation Hub, when completed in 2015, will serve more than 200,000 daily commuters and millions of annual visitors from around the world.
The Hub’s “winged” gateway, also known as the “Oculus,” was designed by internationally acclaimed architect Santiago Calatrava. Its street-level entrance features a curved rib roof and soaring arches, leading commuters to the Hub’s underground PATH rail system, 11 New York City Subway lines, 225,000 sq. ft of retail and restaurant space, four office towers at the WTC site, the World Financial Center and the Winter Garden – all of which comprises one of the most extensive underground pedestrian connections in New York City.

Symposium Marks 20th Anniversary of Northridge Earthquake
Posted by Tasha Weiss on November 7, 2013 at 5:12 PM.
The Northridge 20 Earthquake Symposium will take place in Los Angeles on January 16-17, 2014.
Organized by FEMA, the symposium commemorates the 20th anniversary of the magnitude 6.7 earthquake in Northridge, Calif., on January 17, 1994 that resulted in 57 deaths, thousands injured and over $20 billion in direct damage. The earthquake spurred important changes to the current practice of earthquake engineering and risk mitigation worldwide. These changes included modifications to building codes for vulnerable steel structures and multi-unit wood buildings, reexamination of near-field and basin effects for seismic sources and radical modifications to the risk assessment and insurance sectors. AISC is a sponsor of the event and has organized a track of steel sessions, scheduled for January 17.
Northridge 20 will open with a multidisciplinary plenary session, “Northridge Earthquake: Impacts, Outcomes, and Next Steps,” and continue with concurrent technical and educational sessions on a wide variety of related topics. Attendees will have the opportunity to discuss the impacts of the earthquake, highlight accomplishments of the past two decades and identify necessary steps forward to make our communities more resilient to future earthquakes.
More information, including registration details, speakers list, agenda and participating organizations, are available on the event website at www.northridge20.org.
Free AISC Hazard Communication Webinar Recording Available
Posted by Tasha Weiss on November 6, 2013 at 5:25 PM.
If you missed AISC’s safety webinar “Hazard Communication and the Globally Harmonized System (GHS) for Fabricators and Erectors,” you can now watch the free recording and view the presentation slides.
OSHA’s new Globally Harmonized System (GHS) for Hazard Communication requires fabricators and erectors to provide training to their employees on the new standard requirements by December 1, 2013. To help fabricators and erectors learn what the new GHS requirements are, how to comply with them and meet the training requirements, AISC offered the live webinar last month. This webinar is intended for users, not producers, of hazardous chemicals.
“In March 2012, OSHA issued a new Hazard Communication Standard (77 FR 17574), which completely revised the existing 1987 Hazard Communication Standard (52 FR 31852) by incorporating the United Nations Global Harmonization Standard (GHS),” said Lawrence F. Kruth, P.E., vice president of engineering, technology and safety at Douglas Steel Fabricating Corporation (an AISC member and AISC certified fabricator/advanced certified erector), Lansing, Mich., chairman of AISC’s Safety Committee and the webinar speaker. “By December 1, 2013, all employees must be trained on the new label elements and safety data sheet (SDS) format. This webinar will offer guidance on how fabricators and erectors can comply with this requirement.”
You can watch the 75-minute webinar recording and view the presentation slides at www.aisc.org/safety under “Safety Webinars.” The free recording and presentation slides for AISC’s July safety webinar “Arc Flash Safety for Structural Steel Fabricators and Erectors” is also available at the webpage.

Steel Industry to Exhibit at Greenbuild
Posted by Tasha Weiss on November 6, 2013 at 11:30 AM.
For the 10th year in a row, the American Institute of Steel Construction (AISC) and the American Iron and Steel Institute (AISI) are partnering as exhibitors and Silver Sponsors of the U.S. Green Building Council’s (USGBC) 2013 Greenbuild International Conference and Expo, November 20-22 in Philadelphia.
AISC, AISI and the Steel Recycling Institute (SRI) will share a booth (#2931) at the show that highlights steel’s energy and resource savings, as well as its recycling benefits. Each year, based on construction and demolition industry estimates, about 98% of out-of-service construction plates and beams are recycled and 70% of rebar and other structural steel are captured for recycling through demolition and disassembly.
Additionally, steel continues to provide a proven environmentally responsible solution for meeting “green” building requirements in sustainability standards such as the International Green Construction Code (IgCC), ASHRAE 189.1, the National Green Building Standard (ICC-700), and green building rating systems like the USGBC Leadership in Energy and Environmental Design (LEED).
Greenbuild International is the world’s largest conference and expo dedicated to green building. This year’s conference will host an expected 30,000 attendees from 90 countries. For more information, visit www.greenbuildexpo.org.
To learn more about steel’s sustainability benefits, you can visit AISI’s website at www.steel.org, or, visit AISC’s website at www.aisc.org/greenbuild for information on designing for sustainability with steel.
Live Reinforced Steel Design Webinar Next Week

AISC will host a live webinar next Thursday, November 14, on “Design of Reinforced Steel Members.”
This online presentation will provide practical guidance for designing reinforced wide-flange members using the 2010 AISC Specification. Existing design procedures for reinforced members are based on the allowable stress approach, whereas the 2010 Specification is based on strength design. This webinar will present practical design information based on the strength design approach and discuss considerations that affect the strength and stability of reinforced members such as residual stresses and welding distortion.
The 1.5-hour webinar will begin at the following times, relative to time zone:
10:30 a.m. PST
11:30 a.m. MST
12:30 p.m. CST
1:30 p.m. EST
The cost of the webinar is $185 for AISC members, $285 for non-members and $155 for students and educators. (Fees are based on a per-site connection basis. Purchase one site connection and any number of members in your company or organization may view the webinar at that site connection. All attendees are eligible to receive CEUs/PDHs.)
Registrants will receive access to a PDF file of the presentation slides prior to the webinar, CEU/PDH certificates for all attendees upon completion of the live webinar (0.15/1.5 CEUs/PDHs) and complete instructions for accessing the live webinar.

Steel Shots: Special Delivery
Posted by Tasha Weiss on November 4, 2013 at 3:22 PM.
The above photo shows the installation of the signature 125-ft-tall spire element for the recently completed Sutter Health Eden Medical Center (SHEMC) in Castro Valley, Calif. Using HSS members ranging from 4 in. to 22 in., the spire is connected to the main structure by five 16-ft-long steel cantilevered beams using double-ended plate-bolted connections (these five beams were put in place first). Click on the photo to see a diagrammatic view of the spire. Photo: Sutter Health, DPR, Birdair
There’s integrated project delivery (IPD), and then there’s extreme integrated project delivery.
The process that brought together the recently completed Sutter Health Eden Medical Center (SHEMC) in Castro Valley, Calif., is an example of the latter.
The state-of-the-art, 230,000-sq.-ft, seven-story hospital complex, with a total staff of nearly 1,300, takes over for an adjacent 55-year-old hospital building. The $230 million project brought the owner, architect, structural engineer, general contractor and selected trade subcontractors together to form a first-of-its-kind 11-party IPD team to complete a building with a schedule 30% faster than comparable hospital projects in California.
Laser scanning was used as an added quality-control element in order to verify that field construction matched the coordinated 3D models, including confirming the as-built location of the five cantilevered steel beams supporting the spire element outside the building perimeter. The results were used to complete the design and fabrication of the spire structure based on the exact as-built location and rotation of each beam.
Due to the expected settlements of the steel beam tips and standard tolerances in their construction, the design and fabrication of the spire had to take into account the exact as-built locations and origins of the support beams. The whole spire element was fabricated in pieces and transported to the job site, then interconnected together before connecting to the main structure’s support beams. Two cranes were used simultaneously to lift and align the spire at its five support locations and allow bolt tightening.

New Iowa Bridge Designed with Online Steel Bridge Tool
Posted by Tasha Weiss on November 1, 2013 at 9:39 AM.
A newly built short-span steel bridge on V-65 south of Jesup, Iowa, was designed with a new software program called eSPAN140, an interactive web-based design tool for short-span steel bridges up to 140 ft. Developed by the Short Span Steel Bridge Alliance (SSSBA), this free tool provides an all-in-one resource for steel fabrication and erection details including rolled beam, plate girder, corrugated steel pipe and structural plate.
The first-of-its-kind demonstration bridge replaces a 22-ft-wide bridge that was built in 1947 and had a sufficiency rating of less than 50, making it a prime candidate for replacement on one of the busiest roads in Buchanan County, Iowa. The new bridge is 40 ft wide with galvanized steel rolled-beams and galvanized rebar. Construction began in late August and was completed this week.
A ribbon-cutting ceremony will be held for government and transportation officials at the bridge today from noon to 2 p.m.
U.S. Bridge (an AISC and NSBA member) donated the fabrication of the steel beams and shear studs, as well as the steel material and fabrication of the steel bridge railing. They also donated the modeling and steel detailing of the beams and railing assemblies. Nucor-Yamato Steel (an AISC member) donated the rolled beams and girders for the project and its fastener division donated fasteners for the superstructure. Skyline Steel (also an AISC member) provided the H-piles for the Integral Abutment system and St. Louis Screw and Bolt (an AISC and NSBA member) donated the shear studs. AZZ Galvanizing (an AISC member) donated hot-dip galvanizing services for the project and Big R Bridge (an AISC and NSBA member) provided the project plan review.
The demonstration bridge project is a joint effort with West Virginia University, the University of Wyoming and Iowa State University.
To view a history of the progress of the bridge, including its fabrication, delivery and installation, visit the SSSBA blog or see the live, onsite Webcam, which also provides a time-lapse video of the project.
The eSPAN140 software program is available at www.espan140.com and requires just three steps:
1. Users create a free account (this allows the user to save, share and edit all of the input designs for future use).
2. Users input information about a specific project, including span length, number of striped traffic lanes, skew angle and design speed, among other requirements.
3. eSPAN140 then provides a customized “Solutions Book” PDF based on the specific input provided.
The Solutions Book includes standard designs and details, plate girder and rolled beam recommendations, culvert and structural plate options, customized prefabricated manufacturer steel solutions, durability solutions, a listing of key industry contacts and complimentary design support via the Bridge Technology Center. It also includes design details such as elastomeric bearings, bearing stiffeners, intermediate and end diaphragms and connections and modular bridge and coating systems provided by SSSBA member companies.
