SEISMIC PERFORMANCE AND SHEAR RESISTING CAPACITY OF STEEL PLATE REINFORCED CONCRETE COUPLING BEAMS
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.
