【摘要】 为研究多层结构中双向单排配筋L形剪力墙的抗震能力和力学特性,设计了2个1/2缩尺的双向单排L形配筋混凝土剪力墙结构单元模型,在轴压比确定的条件下,沿翼缘方向和腹板方向分别进行了低周往复荷载试验,分析了试件的承载能力、刚度、滞回特性以及抗震性能。结果表明:工程轴向的承载力和耗能能力都优于非工程轴向,实际工程中采用这种节点是可行的。更多还原

【Abstract】 In order to study the aseismatic propertity and mechanical capability on the residential structure of multi-story L-shear wall structure with bi-directional single row of steel bars,two 1/2 reduced scale’s L-shear wall with bi-directional single row of steel bars models with certain reforcement ratio of RC are designed,separately along the web plate direction and the flange direction,the load-carrying capacity,stiffness,degenerated process and aseismatic behavior of the two models are analyzed,and the horizontal load-carrying capacity is evaluated.Based on the experiments results,it indicates that in the same reinforcement ratio of RC share wall,the load-carrying capacity and energy dissipation capacity of the engineering axial is superior to that of non-engineering axial,therefore it is feasible to adopt this node in practice.更多还原
