Digital Canal Offers New Version of Frame Analysis and Design Software
Posted by Tasha Weiss on July 18, 2011 at 12:03 PM.
Digital Canal Corporation has released an enhanced version of its Frame Analysis & Design software for AutoCAD 2012, 2011 and 2010 (for 32 or 64-bit computers).
In addition to being compatible with the latest versions of AutoCAD, the new software features various updates to its integrated Steel and Spread Footing design capabilities. It includes the AISC 13th Edition (ASD & LRFD) Manual and previous AISC codes (ASD 9th Edition and LRFD 2nd Editions). And its steel shape database now includes rectangular, square and round HSS sections. Additionally, users can search the database more thoroughly and quickly than with previous versions – particularly for HSS and angle shapes.
For more information on Frame Analysis & Design, contact Digital Canal at 800-449-5033, email email@example.com or visit www.digitalcanal.com/structural.htm.
Steel Shots: Look What Flew in Overnight!
Posted by Tom Klemens on July 15, 2011 at 1:11 PM.
This 170-ft-long horizontal truss was hoisted into position overnight on June 28-29 at Iowa State University’s Jack Trice Stadium. It will support an HD video screen measuring 88 ft from corner to corner, making it one of the largest in college sports. Photo: Erik Raker (Click photo to see video coverage of the lift.)
A huge new steel truss will support the new scoreboard being installed on the north end of Iowa State University’s Jack Trice Stadium. The new scoreboard straddles the existing three-story Jacobsen Athletic Building. The steel truss was assembled on the ground starting in early June, while the tower legs were also put into place. The truss was hoisted into place overnight on June 28-29.
AISC member Northwest Steel Erection, Grimes, Iowa, did the erection which included one big lift once the truss was completely assembled. To handle the roughly 180-ton pick required one 600-ton crane and another 550-ton crane. The two-hour lift began about 11 p.m. on Tuesday night, June 28, and by 1 a.m. the truss was being lowered onto the towers.
AISC member H&R Steel Detailing, Kearney, Mo., also was involved in the project, as were AISC professional member Erik Raker, P.E., of Raker Rhodes Engineering LLC, Des Moines, Iowa; the project management team from Construction Products Distributors (a Weitz company), Des Moines, Iowa; and Daktronics, Brookings, S.D.
To see a 2-1/2 minute new clip about the lift from the local TV station, KCCI, click here.
Watch a time lapse video of the lift that highlights the crane operators’ great coordination on the Iowa State Cyclones’ website by clicking here. Be sure to notice the do-si-do-like maneuver as they swing the truss to clear the booms.
To watch the ongoing construction via the ISU stadium live webcam, click here. From the Stadium Scoreboard Webcam page, you can also select archival photos, taken at noon each day, and follow the construction day to day. (The first tower went up about June 1, for example, and just yesterday they started mounting the video display panels.)
2011 NASCC Proceedings Now Available
Posted by Tasha Weiss on July 14, 2011 at 10:23 AM.
While there’s no substitution for attending NASCC: The Steel Conference in person, AISC offers the next best thing. The proceedings document much of the material presented at the conference, including a synchronization of the speakers voices along with their PowerPoint presentations. The 2011 NASCC proceedings are now posted at www.aisc.org/2011nascconline, and you can find previous conference seminars online by visiting www.aisc.org/freepubs and clicking on “online conference proceedings.”
Technical sessions from the 2011 Structural Stability Research Council’s Annual Stability Conference (held in conjunction with The Steel Conference for the 10th consecutive year) are also now available on a flash drive. Visit SSRC’s website at http://www.stabilitycouncil.org/html/pub
2011.html for more information.
Next year, for the first time ever, The Steel Conference is co-locating with the World Steel Bridge Symposium in Dallas April 18-21. Find out more about the 2012 NASCC at www.aisc.org/nascc.
Peddinghaus and Tekla Offer Joint Webinar July 20
Posted by Tasha Weiss on July 13, 2011 at 9:06 AM.
Peddinghaus and Tekla are teaming up to demonstrate Adnexxus - the latest software development connecting building design to shop floor fabrication. To join this free webinar on Wednesday, July 20, at 1 p.m. Central Time, register at the event website, here.
Previously, transferring part data from Tekla structures to an intermediary file format presented complications for machine operation. Adnexxus software allows Tekla data to be directly translated into Peddinghaus CAM files, eliminating the need to rely upon an intermediary file standard and its associated complications.
Adnexxus software allows users to:
- Streamline the production of machine program files
- Quickly organize and modify programs with minimal effort
- Enhance parts programs by including never before applied data directly from the BIM model
- Enhance machine productivity by applying custom program enhancements to an entire job or phase of a project

AISC Rolls Out Sustainability Course
Posted by Tasha Weiss on July 12, 2011 at 9:34 AM.
AISC’s new course, “Sustainability and Steel,” has been approved by The U.S. Green Building Council (USGBC) and will soon be offered for one hour of LEED/GBCI continuing education credit. Those who attend these live learning presentations will report the credit hour directly to GBCI and receive certificates of completion from AISC. Stay tuned for more information about when and where this new course will be available.
The green building movement is increasing at a rapid pace. More and more building owners, architects, engineers and contractors are realizing the benefits of sustainable design and construction practices in improving not only the longevity of the earth’s environment but also the quality of the built environment. This course explains why environmental impact should be a consideration with any new or renovated building and discusses the sustainable attributes of structural steel.
For a more detailed description about this course, visit USGBC’s website at https://www.usgbc.org/CourseCatalog/cour
Deadline Looms for Steel Fabricators to Contact EPA
Posted by Tasha Weiss on July 11, 2011 at 9:09 AM.
Firms primarily engaged in Fabricated Structural Metal Manufacturing and not previously covered as “major emitters of hazardous air pollutants” have until July 25, 2011, to submit an Initial Notification of compliance to the EPA. AISC believes the vast majority of shops will be covered by this rule. AISC director of research Thomas J. Schlafly explained this and other nuances of the National Emission Standards for Hazardous Air Pollutants, 40 CFR Part 63, and how they affect fabricators in the April 2011 issue of MSC.

Steel Shots: A Turkish Bridge

Martin Anderson, an information specialist in the AISC Steel Solutions Center, sent us two photos of this interesting pedestrian bridge from his recent trip to Turkey.
“The Ihlara Valley is a 10-mile long gorge that cuts through part of central Turkey, in Cappadocia,” Anderson wrote. “Famous for the ancient dwellings and churches cut into the sides of the rock, the valley is a popular scenic attraction with hikers. As part of development plans, bridges have been placed over the stream running through the valley, and we’re pleased to note that one of the footbridges uses castellated steel beams with a wooden wearing surface and rails for a lightweight solution that doesn’t intrude on the surroundings.”
One thing to note is the use of small plates inserted between the two halves of the castellated beam. We asked Brian Ward of CMC Steel Products to shed some light on the extension. “By putting the extension plates in they have increased the moment of inertia about the horizontal axis,” Ward said, “and that’s real benefit of the product.” Moving more of the material further away from the neutral axis means a greater resistance to bending, all other things being equal. And depending on the thickness of the material, Ward said you can spread the pieces a bit and still not make it a slender shape.
Why not just go to a deeper beam? One reason might be the concern over total weight. “To go from the lightest W21 to the lightest W24, for example, means going from 44 pounds per foot to 55 pounds per foot,” Ward said. “But adding by a 3-inch extension plate you can get the extra depth with a nominal increase in weight per foot.” He also notes that in his experience use of octagonal openings is rare for castellated beams.
