RESEARCH ON THE BEHAVIOR OF SHEAR WALL COUPLING BEAMS WITH DIFFERENT REINFORCEMENT LAYOUTS
By using the finite element method,the research is carried out on the aseismic performance of shear wall coupling beam with 4 kinds of reinforcement layouts: conventional (standard),simple diagonal,rhombic,and diagonal with transversal ties. The comparison analysis about load-deformation,shear resistance,and ductility are presented. The results show that the rhombic layout shows superiority in terms of ductility and shear-bearing capacity. A 18-story building is selected as the studies case to investigate the aseismic performance of shear wall with standard and rhombic layout coupling beams in the case of the monotonic loading. Numerical results show that the shear wall with rhombic layout coupling beams has a 44％ higher shear resistance,51％ higher roof displacement and a 97％ higher ductility factor compared to that of shear wall with standard layout coupling beams. The optimal seismic performance in terms of shear resistance and ductility,simplicity of detailing,makes the rhombic layout coupling beam an attractive choice.
