Abstract
This paper considers the effect of transverse and bending reinforcement on the in-plane mechanical behaviors of composite slabs with precast ribbed panel (CSPRP). A standard reinforced CSPRP was designed and built, another four specimens were obtained by removing or doubling the transverse/bending reinforcement for comparison. All of the specimens were tested under in-plane low cycle reversed loading by following Chinese standard for structure test method. The failure mode, bearing capacity, displacement, ductility, energy dissipation capacity and stiffness of these specimens were investigated and compared. As expected, the range of cracks, and ultimate displacement and energy dissipation capacity increases with transverse/bending reinforcement. The ductility of the specimens does not exhibit a clear trend with the changes of transverse/bending reinforcements. Transverse/bending reinforcement have a little effect on stiffness of specimens.
