带约束拉杆双钢板混凝土组合剪力墙抗震性能数值模拟及参数分析
Numerical Simulation and Parameter Analysis on Seismic Behavior of Composite Concrete and Double Steel Plates Shear Walls with Binding Bars
摘要
Abstract
In order to study the seismic behavior of composite concrete and double steel plate shear walls with binding bars,sixteen specimens were tested under reversed cyclic lateral load,and the numeri-cal simulation by using the analytical software OpenSees was also conducted for the composite concrete and double steel plate shear walls.On the basis of experimental and numerical analysis,the main parameters affecting on the seismic behavior of the composite shear walls were evaluated.All the results indicate that the factors of aspect ratios,axial compression ratios,and binding bar spacing significantly affect the seis-mic behavior of the composite shear walls.As the aspect ratios of the composite concrete and steel plate shear walls increase,the initial stiffness,peak load,yield load,post-yield stiffness,and energy dissipation capacity decrease obviously.The axial compression ratios exhibit an effect on the degradation of the post-yield stiffness.In addition,the close spacing of binding bars can improve the bearing capacity and energy dissipation capacity of the composite shear walls,and reduce the degradation of the post yield stiffness.关键词
