Steel frame listings to be included
design issues related to the use of steel in design and construction. A total of $14,000 in cash prizes was awarded to the winning students and their faculty sponsors. Students submitted designs in two catego-
in U.L. Fire Resistance Directory Two successful full-scale fi re tests conducted by the American Iron and Steel Institute (AISI) and the American Institute of Steel Construction (AISC) at Underwriters Laboratories (UL) provide insight for construction professionals strug- gling to decide whether to specify restrained or unrestrained fi re protection thicknesses for structural steel-framed buildings. The answer is that the required fi re protection will be the same, at least for the fl oor construction described in the new U.L. Design No. D982. AISI and AISC conducted tests of two unre-
strained structural steel-framed fl oor specimens with 4 1/2 inches of normal weight concrete over steel deck supported by a W-shape beam. The fi rst test was conducted on January 8 and ran for 2 hours and 32 minutes before the loading mechanism reached its limit. The second test was held on March 13 and ran for 2 hours and 29 minutes before the limit was reached. Both tests exceeded expectations. "Based on tests that the steel industry con-
ducted 30 years ago and on empirical observations made since then, we have always advocated that restrained ratings are applicable for the vast major- ity of structural steel-framed building designs," says Robert Wills, PE, vice president, construction market development for the Steel Market Development In- stitute, a business unit of AISI. "These new tests give the steel industry the opportunity to update the state of fi re science and document for a new generation of architects, engineers and code offi cials that steel- framed buildings can be designed with fi re protection thicknesses that are both safe and cost-effective." The new UL Design No. D982 provides for two-
hour unrestrained assembly ratings with unprotected steel deck and SFRM (spray-applied fi re resistive ma- terials) protection on the steel beam with thickness suffi cient to obtain a one-hour unrestrained beam (temperature-based) rating.
Winners announced in 13th annual ACSA/AISC Steel Design
ries that required steel to be used as the primary structural material and with special emphasis placed on innovation in steel design. The Bridge to Building category challenged students to design a pedestrian bridge that would enrich its location and provide a vital spatial connection, as well as include an ancillary function, a small pavilion that supports the cause for the crossing. In the Open Category, students were given the opportunity to select a site and building program that included at least one long-span steel structure. More information can be found at
