Curved Steel Design Innovations at AIA
Posted by Tasha Weiss on May 14, 2012 at 11:44 AM.
Are you planning to attend the AIA Convention and Expo this week in Washington, D.C.? If so, you have the opportunity to learn about the latest innovations in curved steel and how it can enhance the creativity and efficiency of your next design.
When you visit AISC’s booth (#1615) at the show and mention “curved steel,” you’ll gain first-hand knowledge on the subject from industry experts (who actually curve steel!) and receive a free copy of the Curved Steel Guide for Specifiers, along with the new Curved Steel Quick Reference Guide for architects.
As an added bonus, ask the AISC staff in the booth about this year’s SteelDay and receive a prize!
Unable to attend the AIA Expo? You can request the Curved Steel resources from AISC’s Steel Solutions Center at firstname.lastname@example.org.
Just look at the majesty of this exposed curved steel building! This photo is of the Ave Maria University Oratory in Ave Maria, Fla., a 2008 AISC IDEAS2 Award winner. Photo: Cannon Design

Last year, SteelDay introduced a creative element to its national program. The SteelDay Sculpture Competition challenged AISC Full and Associate Members to build an innovative steel sculpture to be displayed on SteelDay as well as this year’s NASCC in Dallas, where the winner was voted on by conference attendees.
Eight sculptures were entered into the competition. The winning sculpture was “The Welder,” submitted by Cody Builders Supply, an AISC member fabricator in Austin, Texas. Weighing in at 140 lbs and made mostly of 1/4-in.-thick plate, the sculpture pushed the size limit for the competition and is exactly 2 ft tall (and just look at that detailing work!).
You can view all eight entrants at SteelDay’s Facebook page. The Welder will also be featured in the June issue of MSC, available June 1.
This year’s SteelDay is set for September 28, and will once again offer the opportunity to display your works of steel! Information on this year’s events can be found at www.aisc.org/steelday, where continuous updates will be provided as plans are rolled out. Interested in hosting an event this year?

Huey P. Long Bridge in the Home Stretch
Posted by Tasha Weiss on May 9, 2012 at 4:35 PM.
Last month’s opening of the new lanes on the Huey P. Long Bridge has been long-awaited by New Orleans locals. Traffic was switched from the bridge’s old lanes to two new lanes in each direction, bringing the $1.2-billion widening project one step closer to completion.
The traffic switch allowed the old lanes to be removed and the new travel lanes to be widened. Instead of completely replacing the bridge, bridge engineering firm Modjeski and Masters designed a steel support system to widen the existing truss. When completed, the bridge will also feature an additional travel lane and inside and outside shoulders to each side of the bridge, and the total driving surface width will be more than doubled, providing a safer, more reliable Mississippi River crossing.
The first phase of the expansion project began in April 2006, and the bridge is now in its final phase of construction. The entire project is slated to be completed in early 2013.

Miller and Hobart Brothers Picked for Lambeau Expansion
Posted by Tasha Weiss on May 8, 2012 at 4:51 PM.
Welding equipment manufacturer Miller Electric, Appleton, Wis., and filler metal manufacturer Hobart Brothers Company, Troy, Ohio, have been named the official welding equipment providers of the expansion of Lambeau Field, home of the Green Bay Packers.
The two manufacturers have also partnered with Neenah, Wis.-based general contractor Miron Construction Co., Inc. to provide the project team with the latest in welding and heat treatment technologies, as well as welding safety gear. The companies have worked together to convert traditional processes to new methods of improving weld quality, productivity and safety, such as using Flux-Cored welding techniques and induction heating systems in structural steel applications.
“Welding isn’t often the first thing people think of when they think of the construction industry,” commented Mike Weller, president of Miller. “But it is one of the most critical elements of a heavy structural job like this and provides us with the perfect opportunity to showcase these technologies.”
The Lambeau Field expansion will be completed in 2013 and involves substantial new construction to both end zones, including 6,600 new seats in the south end zone and new high-definition video boards in both end zones; about 5,000 tons of steel is being used for the expansion. Both video boards and a new viewing terrace in the north end zone will be operational in time for the 2012 football season.

About 200 student engineering teams across North America participated in a total of 18 regional competitions since January. The competition challenges teams with building their own designed and fabricated steel bridges under the pressure of the clock. Bridge rankings are based on a variety of factors, including: construction cost, construction time, total bridge weight and bridge stiffness.
“The students that participate in this competition demonstrate great design and management skills, and impressive ingenuity,” commented Nancy Gavlin, AISC director of education. “Their dedication and enthusiasm for their work is a joy to observe.”
If you’ll be in the Clemson, S.C. area, witness this exciting and fast-paced competition for yourself (admission is free), and see if your school gets crowned the national champion! Visit www.aisc.org/steelbridge or www.clemson.edu/steelbridge to learn more.

Every year, AISC’s IDEAS2 Awards recognize the most innovative new steel structures in the U.S.
This year’s 10 IDEAS2 winners were announced at the 2012 NASCC: The Steel Conference last month in Dallas. Covering an array of project types, they demonstrate the flexible and effective solutions provided by structural steel on a wide variety of building projects.
A panel of design and construction industry professionals identified National and Merit winners in three categories, based on constructed value: less than $15 million, $15 million to $75 million and greater than $75 million. In addition, the panel awarded a Presidential Award of Excellence to one project for structural engineering and architectural accomplishment.
All of this year’s winners are featured in the May issue of MSC (available now!), with detailed project descriptions and photographs of each; you can read the article here.

One WTC Now New York’s Tallest
Posted by Tasha Weiss on May 1, 2012 at 11:30 AM.
Yesterday marked a major milestone for One World Trade Center, as installation of the steel columns on the 100th floor made the skyscraper the tallest building in New York City. Now 1,271 ft tall, it has surpassed the Empire State Building, previously the city’s tallest structure.
Scheduled to be completed in late 2013, the tower is slated to reach 104 stories. An antenna reaching hundreds of feet higher will bring the total height to a symbolic 1,776 ft, which will make it not only the tallest building in New York, but also the entire U.S.
You can watch a video of a steel beam being placed atop the tower at www.cnn.com (direct link: http://bit.ly/IH2ffZ). For more information about the project’s construction progress, visit www.panynj.gov/wtcprogress/one-wtc.html.
