2009 NASCC Proceedings

Rather than waste paper or disks, the 2009 NASCC: The Steel Conference proceedings will only be available in online format. As papers are submitted, they will be posted (not all presenters will prepare a paper and some presenters will provide their actual presentations). Feel free to print these to use as notes during the sessions.

For more information on The Steel Conference, visit www.aisc.org/nascc.

 

C4 C4 - Design of a Steel-Framed Industrial Building with Overhad Cranes: Session I (James Fisher)
C4a - Calculations for Session C4
C5 C5 - Design of a Steel-Framed Industrial Building with Overhad Cranes: Session II (Jules Van de Pas)
C5a - Calculations for Session C5
C5b - Appendicies for Session C5
C8 C8a - Calculations for Design of a Steel-Framed Industrial Building with Overhad Cranes: Session V
D6 D6 - How to Get Rich in Detailing (Hugh Dobie, Dowco Consultants)
This session examines what makes a successful detailing business and once successful, what the detailer should do to prepare for retirement and ownership transition.
E3 E3 - Gusset Plates for Seismic Construction (Charles W. Roeder, Dawn E. Lehman)
E3a - Gusset Plates for Seismic Construction (William Thornton, Larry S. Muir)
E4 E4 - Structural Integrity in Buildings (Kurt Gustafson)
E9 E9 - Design of Frames Using Web-Tapered Members (Donald White, Georgia Institute of Technology)
AISC’s upcoming design guide, being developed in conjunction with MBMA, will present a comprehensive approach to the design of frames composed of web-tapered members within the context of the 2005 AISC Specification for Structural Steel Buildings. A preview of MBMA/AISC Design Guide 25, Design of Frames using Web-Tapered Members, will be presented along with an example for a typical clearspan gabled metal building frame. The presentation will emphasize key concepts as well as similarities and differences with respect to previous AISC provisions for design of these types of structures.
E11 E11 - Hollow Structural Section Connections Design Guide (Jeffrey A. Packer)
E13 E13 - The Process of Renovation-Concept to Completion! (Stanley Wojnowski, Buro Happold Consulting Engineers)
Can the existing steel members be reused on a major renovation project? This presentation will provide a step-by-step guide to developing a systematic sequence for renovation projects centered on incorporating and reusing the existing steel members. Several recent New York City projects will be used as examples.
E15 Better Base Plates by Design (Barry K. Arnold)
E17 E17 - Cold-Formed and Hot-Rolled: The Best of Both Worlds (Roger LaBoube, Missouri University of Science and Technology)
Cold-formed steel products have been used by the pre-engineered building manufacturers for roof and wall framing for years. This session will give you the knowledge to adapt cold-formed steel products to conventional steel framing. Design approaches and procedures will be given to include design guides, section properties, and shortcuts. The session will conclude with examples and details of practical use with conventional framing.
E27 E27 - Developments in the Design of Bolted Connections: Bolt Shear Strength and Slip Resistance (R.H.R. Tide)
E27a - Slip Critical Connections Design Specifications and Current Research (L.A. Kloiber, P.E. and T.J. Schlafly)
F12 F12 - Developing a Sustainable Business (Richard Barrett, Barrett Structures)
Have you wondered how to develop a sustainable policy suitable to your business operations? Learn from one fabricator who started the process in 2006 and became one of the first steelwork contractors in the world to have calculated their own carbon footprint! The session will cover the process from undertanding your company’s reasons for thinking about sustainability to the economic impact to the impact on the community and the environment.
F13 F13 - The Bow EnCana's New Corporate Headquarters in Calgray (Barry Charnish, Halcrow Yolles)
The Bow is the latest design by Foster Partners of London. This banana shaped 60-story tower features a vast atrium partitioned in four clear height sectors of 24, 18, 12 and 6 stories. The façade of the atrium is an architecturally exposed diagrid structure in six-story segments that act as one of the building’s six lateral force resisting systems. The other LFRS include a W-shaped rigid frame at each end of the banana-shaped structure, and two additional diagrid sectors on either side of a concentric and eccentrically braced area framed through the core. The building also features long-span composite trusses creating core-to-perimeter wall open spaces.
P4 P4 - The Art of Steel (Duane Ellifritt, University of Florida)
How is steel used in art today? This entertaining presentation will look at artwork from the past three hundred years and also give an overview of today’s modern steel sculptures.
R7 R7 - What Does BIM Mean to the Erector? (Steve Rodriguez, Dave Litwin)
R9 R9 - New Developments in Fall Protection (Travis Bergstrom)
X2 X2 - Connections: The Last Bastion of Rational Design (William Thornton)
X3 X3 - Seismic Upgrade of a 15-Story Steel Moment Frame Building: Satisfying Performance Criteria with Application of Experimental and Advanced Analytical Procedures (James O. Malley, Degenkolb Engineers)
This session discusses the seismic analysis and rehabilitation design of a 15-story steel moment resisting frame building constructed with connection details found to be vulnerable to fracture in the 1994 Northridge earthquake. Advanced nonlinear time-history analyses, that included simulation of fracture of the vulnerable connections, were combined with full-scale experimental testing of retrofit connection schemes to validate the retrofit scheme that combines connection retrofit with the addition of viscous damping.
