Steel Shots: Twisted Beams
Posted by Tom Klemens on May 12, 2011 at 11:02 PM.
A full-size test specimen of ConXtech’s ConXL special moment frame (SMF) connection - after being tested - is one of the interesting things to see in the Exhibit Hall this year at NASCC: The Steel Conference.
Full-scale testing of large structural steel connections produces some pretty convincing results. This 6-ft section of a test specimen on display in the ConXtech booth (#1229) at NASCC shows convincing proof that the 30-in wide-flange beams failed before the company’s ConXL connection. Put another way, this proprietary, rapidly connected “lower and lock” connection system develops the full plastic moment of the beam. The connection has been prequalified by the AISC 358 Connection Prequalification Review Panel and will be included in the 2010 Seismic Conditions.

New BIM Integration Introduced at NASCC
Posted by Tom Klemens on May 12, 2011 at 9:57 AM.
Design Data has announced a new integration between its SDS/2 software solutions and Autodesk Revit Structure. It is now being demonstrated, for the first time, at NASCC: The Steel Conference in Pittsburgh.
Based on new technology and interoperability, this increased integration means automated connection design is widely available to the AEC industry professionals inside the tools they are accustomed to using for BIM projects. With it Revit users can seamlessly transfer their models and connections to the steel detailers on the project using SDS/2’s intelligent connection design.
To learn more, go to www.sds2.com or visit booth 1107 at NASCC: The Steel Conference for a demonstration.
Free Thursday Morning Webinar Streaming Live From NASCC
Posted by Tom Klemens on May 11, 2011 at 2:25 PM.
The 2011 edition of NASCC: The Steel Conference opens today in Pittsburgh, but even if you’re not at the conference you can join us for a free webinar Thursday morning. A session just recently added to the program, “Structural Issues: New Zealand and Japan Earthquakes,” will be streaming live from Pittsburgh beginning at 8 a.m. Eastern time. Login to this free 90-minute webinar to hear Alistair Fussell of Steel Construction New Zealand present an overview of the events in his country. Also, Gilberto Mosqueda, who traveled to Japan after the March 11 earthquake, will report on structural damage in that area.
To listen in, go to www.aisc.org/NASCCLive. The webinar begins at 8 a.m. Eastern time on Thursday. May 12.
If you are attending NASCC, come to the Spirit of Pittsburgh Ballroom A to participate in the session, which is included your conference registration. And you may even want to start early, since Thursday is this year’s long and jam-packed day.
Begin at 7 a.m. by choosing from seven 45-minute Exhibitor Workshops. Fortunately some are offered a second time, at 5:30 Thursday or 7 a.m. Friday. (I plan to be at the barcoding presentation by InfoSight.)
Regular sessions begin at 8 a.m., and the Exhibit Hall floor opens at 9.
For a hometown Pittsburgh story, consider the 10 a.m. presentation (N67) covering the new home of the Pittsburgh Penguins (with a steel perspective, of course), which is just up the hill from the convention center. On this project the fabricator and engineer collaborated to optimize member types, connection types, and the interfaces with other trades for simplicity in both the shop and the field.
Another interesting Thursday session (N33) is a presentation by three bender/roller experts about the realities of curved steel. This session starts at 4:15.
Then don’t miss the conference dinner across the Allegheny River at Heinz Field. Busses leave from the convention center beginning at 6:30. As an alternate, it’s just a 1.6 mile walk down Penn Avenue and across the Sixth Street Bridge (aka Roberto Clemente Bridge), which in 1923 was the very first national steel bridge award winner.

New Podcast Features Frank Hatfield, Student Steel Bridge Competition Chair
Posted by Tom Klemens on May 9, 2011 at 3:34 PM.
A newly released podcast in the AISC Steel Profiles series features a conversation with Frank Hatfield, chair of the Student Steel Bridge Competition’s rules committee. Hatfield was first involved in the competition in 1988 as the faculty advisor to the Michigan State University team, which was competing in the second year of the event. (The first competition had been held the year before, in 1987, when Bob Shaw, AISC’s director of university programs, arranged a local student steel bridge competition for three Michigan universities: Lawrence University, Michigan Tech, and Wayne State.)
Hatfield has been helping to organize the competition and write the rules ever since. In 1992, after several years of local competition, he and the Michigan State team issued an open challenge. That year with support from AISC, MSU hosted the first national bridge competition with 13 college teams participating.
Now sponsored by AISC and ASCE, the successor to that early competition has grown into a staggering success. Approximately 200 teams compete in regional competitions representing 47 states, the District of Columbia, Puerto Rico, Canada, Mexico and China.

The 20th National Student Steel Bridge Competition finals will be held at Texas A&M University, College Station, Texas, on May 20-21, 2011. Drop in if you’re in the area – admission is free. Visit the official website for more information.
Steel Shots: A Tunnel to Infinity
Posted by Geoff Weisenberger on May 6, 2011 at 11:00 AM.
Supported by 68 HSS trusses, Brussels Airport’s Pier A resembles an airplane wing. (Click on photo for another view.) Photos: Geoff Weisenberger.
Earlier this spring, I traveled to Brussels, Belgium, for a steel industry event. As would be expected, my final impression of the city was the airport. And what an impression it was!
After winding my way through what seemed to be an endless array of shops, hallways, kiosks and other airport-type installations, I came to the entrance of Pier A, an ultra-modern, steel-supported concourse that appeared to stretch into infinity. In reality, this concourse is 650 m (2,132 ft) long. But thanks to the sleek design—the curvature of the building resembles that of an airplane wing—and perhaps my lack of sleep (not to mention a few glasses of strong, Belgian beer from the night before) it seemed to go on forever.
The pier, which opened in 2002, contains 31 gates and handles flights to Africa as well as flights to and from the Schengen Treaty countries. It also showcases the elegant combination of exposed structural steel and ample daylighting. There are no conventional support columns in the passenger area. Rather, the aluminum skin roof and floor-to-ceiling facades on either side are supported by 68 triangular, 3D, curved, round HSS trusses—950 metric tons in all—which were fabricated and erected by Belgian steel construction company International Metal Works.
As I sat in Pier A, watching the sun rise, waiting for my flight home, I realized something: My architectural image of Brussels had previously been that of heavy, ancient gray stone and cobblestone streets that make you feel as though you’ve stepped back in time.
The light, modern Pier A, by contrast, propels you into the future, thanks in large part to its practical and beautiful use of steel. It certainly prompted me to update my architectural image of the city.

Major Scotland Bridge Replacement a Go
Posted by Tasha Weiss on May 5, 2011 at 1:56 PM.
A panoramic view of the Forth Bridges viewed from the south bank of the Firth of the Forth. On the right is the Forth Railway Bridge, Great Britain’s first steel bridge when it opened in 1890. It’s located east of the newer road bridge.
After 18 months of tenders bidding to design and construct the new Forth Road Bridge, a large transportation bridge in Scotland that spans the Firth of Forth, connecting the southeast capital city Edinburgh to the heavily populated area of Fife in the northeast, Forth Crossing Bridge Constructors (FCBC) has been awarded the main contract for the 2.7 km bridge replacement. The FCBC joint venture includes AISC member American Bridge, HOCHTIEF, Dragados, and Morrison Construction. The contract is valued at $1.3 billion.
A major bridge crossing two ocean shipping and military navigation channels represents the main part of the contract and includes a cable stay structure of 2,020m (the world’s second longest). The two main navigation spans are 650m each (the world’s sixth longest). The bridge has 14 spans, two planes of stay cables that anchor in the center of the structure, and a composite steel tub/concrete deck superstructure. The cable stay bridge superstructure will be erected mainly by deck mounted gantries; the south approach viaduct will be launched from land, and the north viaduct will be pushed from the water. Construction will begin in 2011 and finish in 2016.
More information about the history of the Forth Road Bridge can be found on Wikipedia, here.
