Time Dependent Response and Deformations of Composite Beams with Innovative Deep Trapezoidal Decks

Funding or Partner Organisation: Australian Research Council (ARC Linkage Projects)

Start year: 2008

Summary: The construction industry in Australia is introducing efficient and economical long span trapezoidal profiled steel sheeting for composite flooring systems. Australia is a world leader in the research of composite structures. Composite beams undergo deformations because the concrete creeps and shrinks, and because the slab slips relative to the steel joist. Surprisingly little research has addressed these issues collectively; they are of paramount significance with trapezoidal decks and research is much needed. This research will investigate the interaction of creep, shrinkage and partial interaction in these composite beams, producing valuable design guidance to keep Australian research and practice at the forefront internationally.
