Structural Steel Industry Hosts Third Annual SteelDay September 23

Mark Sept 23 on your calendars for Steel Day.  Some of this year’s topics include Steel Making and Recycling, HSS Producers, Steel Service Centers, BIM, Steel Fabrication, Advanced Machinery and Robotics, and Steel Installation.

(Chicago, IL) – Have you seen what the structural steel industry can do? SteelDay is your opportunity. The industry’s largest educational and networking event returns for a third successive year this September 23. Hosted by the American Institute of Steel Construction, its members and partners, SteelDay is a national event for the design and construction community to explore the structural steel supply chain firsthand.


Starting this year, SteelDay can be found on Facebook. Simply search for “SteelDay” at and “Like” the fan page to access SteelDay photos, updates, and discussions. You can also keep in touch with SteelDay on Twitter ( @SteelDay.

Natural Earthquake Protection System Discovered in Caribbean

MIT’s Technology review has posted an article on how ancient buried mangrove swamps found in the Caribbean can absorb energy from earthquakes and reduce the potential for liquefaction.  The paper was published by Bulletin of the Seismological Society of America; June 2011; v. 101; no. 3; p. 1073-1080; DOI: 10.1785/0120100129

This buried mangrove layer is remarkably flexible and this has an important effect on the energy generated by earthquakes. “The buried mangrove layer plays the role of an isolation system,” say Guegen and co. It absorbs energy and protects the ground above from the worst effects of an earthquake. “The flexibility of the mangrove layer reduces the distortion and the stress in the sandy upper layer, and consequently reduces the potential of liquefaction of the site,” they say.


Analyzing Urban Traffic Statistics with Wolfram|Alpha

Traffic statistics is yet another topic that Wolfram|Alpha can analyze.  The Wolfram|Alpha blog gives some examples for the usage.

New York City. Los Angeles. Chicago. Each of these cities is renowned for a diverse array of cultural, entertainment, culinary, and other experiences—as well as for legendary traffic delays. But just how bad do native commuters have it? And if you drive to work in a different city, how does your commute stack up? Wolfram|Alpha can’t yet guide you through the traffic, but it can visualize and compare statistics about traffic and urban transportation in more than 100 US urban areas, with data from the Texas Transportation Institute’s Urban Mobility Report.

Steel Bridge Design Handbook has an online Steel Bridge Design Handbook.  The initial Chapters and Design Examples of the renamed Steel Bridge Design Handbook are available for download on their website.  The examples are quite informative.

The original Highway Structures DesignHandbook was produced by US Steel in the 1970s. The project was subsequently taken over by AISC Marketing. Now, with federal grant money, NSBA with HDR Engineering, Pittsburgh, PA as the Principal Engineer, is undertaking the much-needed updating of this important industry document. Eventually, it will encompass 23 chapters and seven Design Examples. The chapters are being written by prominent engineers in the field and reviewed by a committee organized by NSBA. Comments are compiled by NSBA, returned to the authors for revisions, and then finalized by NSBA.
