New Steel Design Guide for Web-Tapered Members
Posted by Tasha Weiss on August 15, 2011 at 8:46 AM.
AISC Steel Design Guide No. 25, Frame-Design Using Web-Tapered Members, is now available as a free download by AISC members at www.aisc.org/dg or can be purchased by others. This latest addition to the AISC design guide series provides guidance on the application of the provisions of the AISC Specification for Structural Steel Buildings to the design of web tapered steel members and steel frames composed of web tapered members. A discussion of fabrication is included, as well as a detailed description of stability design requirements for web-tapered members. This design guide is based on the 2005 AISC Specification for Structural Steel Buildings; however, the recommendations of this document apply equally to the 2010 AISC Specification for Structural Steel Buildings, although some section and equation numbers have changed in the 2010 Specification.
Huey P. Long Bridge Tops Out
Posted by Tasha Weiss on August 12, 2011 at 9:41 AM.
The final piece of steel in the Huey P. Long Bridge Widening Project was lowered into place at the top of the bridge in New Orleans on July 26. There is still some work to do on the truss above the roadway (the superstructure), but all of the steel members are in place. Photo: Louisiana TIMED program.
Widening the Huey P. Long Bridge is part of Louisiana’s $5 billion Transportation Infrastructure Model for Economic Development (TIMED) program, which includes two other major bridge projects and widening 536 miles of state highways.
This four-phase widening project has been long-awaited by local communities and is vital to the recovery of the Greater New Orleans area. According to the project website, it will add an additional travel lane and inside and outside shoulders to each side of the bridge - providing a safer, more reliable Mississippi River crossing. The first phase of the project began in April 2006 and the entire project will be complete in 2013.
View additional photos of the topping out and other Huey P. Long Bridge milestones, as well as other La. bridge projects, in the project manager’s photo gallery at www.timedla.com/gallery.
We’ve been tracking Huey P.’s progress for a while now and hope that you’ve enjoyed its journey with us. For more information and background on the project, visit the project website www.timedla.com/bridge/long/overview and take a look back at one of our previous news posts commemorating Huey P.’s Last Big Lift, here.

2012 Student Steel Bridge Contest Rules Available
Posted by Tasha Weiss on August 10, 2011 at 8:39 AM.
The 2012 ASCE/AISC Student Steel Bridge Competition rules have been posted on the AISC website. Among other changes, the formula for determining structural efficiency has been reworked for 2012, generally increasing the cost based on weight compared to the deflection-based cost.
The site conditions for this year’s challenge prohibit the use of temporary piers or barges in the river, although there will be a midstream cofferdam (furnished by others). The bridge again requires a cantilever section on one end, although the bridge dimensions have been changed from last year. Numerous other updates have been incorporated into the 2012 rules.
The preliminary round of bridge competition consists of 18 regional events held each year throughout the spring. The 2012 National Competition will take place at Clemson University on May 25-26.
To view the rules and other Student Steel Bridge Competition related information, go to www.aisc.org/steelbridge.
To watch the Lakehead University team, which was the fastest at the 2011 national competition, build its bridge in just less than five minutes, go to http://bit.ly/jLQvFc.

Steel Shots: A Memorial Beam
Posted by Tom Klemens on August 5, 2011 at 10:07 AM.
A flag-draped steel beam from the World Trade Center arrives in Indianapolis. This and and a second beam will be the focal points of the Indianapolis 9/11 Memorial being erected beside the White River Canal at 421 West Ohio St. Photos: Indiana Steel Fabricating, Inc.
Two 22-ft-long steel beam sections from the World Trade Center are well on their way to anchoring a new memorial in Indianapolis that will be dedicated on September 11, the tenth anniversary of the terrorist attacks in New York. Greg Hess, an Indianapolis firefighter and paramedic, initiated the campaign 18 months ago to establish the memorial. He and his colleagues in Indiana Task Force 1, a FEMA search and rescue team, spent eight grueling days laboring alongside other rescue workers in New York following the collapse of the towers.
As the beams left the hangar at JFK Airport in New York and traveled to Indiana they were accompanied by a sizable motorcade. Reports documenting the trip include estimates that there were at times more than 11,000 riders stretching over 50 miles. For one look at photos and video of the procession, visit http://bit.ly/oH16rc, the website of an Indiana motorcyclists club.
AISC member Indiana Steel Fabricating, Inc., Indianapolis, received the beams on July 18 and installed the necessary base plate assemblies. The beams will be erected as two columns at the memorial. A life-size bronze American Bald Eagle will sit atop one of them with its wings outstretched and looking toward New York.
The thumbnail photo (right) shows the two World Trade Center beams with base plates in place leaving the Indiana Steel Fabricating facility. (Click on thumbnail to view a larger image)
The beams will be on display at the Indiana State Fair beginning today through August 19. The fair opens today at the Indianapolis Fairgrounds on the north side of the city.
You can see a rendering of the artist’s intent on the project website, www.project911indianapolis.org. A video clip of the July 21 groundbreaking as reported by WISH-TV is also available on the website (select “In the News.”)
