GIRDER-SLAB ® SYSTEM HISTORY
Conventional wisdom for using steel has been to maximize spans and provide universal products that fit nearly any building type. Girder-Slab Technologies, LLC chose a rather unorthodox approach to find a solution. First, we determined that precast slab units, common in the mid-rise residential market, combined with a steel frame could offer speed, design flexibility and value. Although residential unit modules typically vary within a floor, they generally stack vertically for structural support, utilities and shafts. After considering the modular nature of residential construction, it was concluded that long-span precast slabs in combination with short span steel girders would be both appropriate and efficient. Our D-BEAM® girder overcame the issue associated with a standard wide flange beam sitting below the slab.
THE D-BEAM® GIRDER
The D-BEAM® girder fabrication process begins with a standard wide flange section that when uniquely cut through the web produces two equal T sections. The fabricator then welds a flat bar to create the top flange resulting in two D-BEAM® girders from one parent beam without waste. With practically an unlimited source of supply, the D-BEAM® girder is manufactured by your local steel fabricators as part of a complete structural steel package.
INDUSTRY RECOGNITION AND ACCEPTANCE
The GIRDER-SLAB® system and its principals have been recognized for making a positive and substantial impact on the structural steel design and construction industry, specifically for its contribution as a structural steel based solution to multi-story residential structures. Additionally, Girder Slab founding principals have received AISC Special Achievement Awards, as well as the AISC Lifetime Achievement Award. These awards provide special recognition to those who demonstrated notable achievements in structural steel design, construction, research, or education.
