Seismic Performance and Shear Resisting Capacity of Steel Plate Reinforced Concrete Coupling Beams
Abstract eng: Coupling beams of coupled shear wall system in seismic regions are required to have high load resisting capacity and excellent ductility and energy-dissipation capacity. To achieve this goal, the concept of steel plate reinforced concrete coupling beams (SPRCCB) is proposed. 6 SPRCCB specimens, 4 with a span-depth ratio of 1.5 and 2 with a span-depth ratio of 2.5, were tested under cyclic loading. Test results of the specimens are discussed. To further investigate the role of the steel plate in a SPRCCB, non-linear FE model based on one of the tested specimens was set up and verified. Based on this model, a parametric study was carried out to investigate the effect of the steel plate reinforcement ratio, the depth, thickness and depth-thickness ration of the steel plate on the shear resisting capacity of a SPRCCB. Some design recommendations were proposed based on the experimental and the analytical results.
