SpeedCore and Steel-Concrete Composite Construction - The Best of Both Worlds- View Only

The merits of steel-concrete composite construction have been recognized and leveraged for decades, but they have never been harnessed quite so efficiently as the new SpeedCore system, which consists of composite plate shear walls and composite coupling beams. This system can be used, when needed, in lieu of traditional reinforced concrete core walls/shear walls in commercial, industrial, or nuclear construction. The primary advantages of this composite system stem from the efficient modularization and prefabrication of steel modules, and the elimination of rebar cages, formwork, and falsework, resulting in an expedited construction schedule and thus overall increased project economy. In this year’s T.R. Higgins Lecture, Purdue University’s Amit Varma will summarize the results of extensive research conducted over more than 12 years, culminating in the development of design specifications, provisions, and guidelines for composite walls and systems for various applications. He’ll highlight experimental behavior, numerical modeling, and design of composite walls and the SpeedCore system for wind loading, seismic loading, and fire loading conditions. For wind loading, the presentation will focus on stiffness and strength. For seismic loading, the presentation will focus on the capacity design method and performance evaluation. For fire loading, the presentation will cover both the fire resistance rating (in hours) and strength at elevated temperatures.
