摘要

剪力墙与板节点的可靠性是保证板发挥横隔作用,使各剪力墙板、协同工作,形成空间受力体系的关键。在已完成试验的基础上,结合有限元方法,对可能影响其抗震能力的多种参数,包括剪力墙轴压比,连接钢筋强度、直径、数量及长度,以及板受力纵筋配筋率等,进行了详细分析和比较。指出全预制装配整体式剪力墙结构墙板节点的抗震能力主要由连接钢筋的配置情况及其与板抗弯能力的协调作用效果决定。
Reliability of shear wall and floor joint is the key for ploor to play transverse partition effect and make coordinated working with shear wall to form spatial force system.On the basis of finished tests and combining with finite element method,detailed contrast and analysis has been done on various parameters affecting the joints' seismic capacity,including different axial compression ratio of shear wall,the strength,diameter,quantity and length of connection steel bar,as well as the reinforcement ratio of floor.It is pointed out that the seismic performance of wall and floor joint for the new precast concrete shear wall structure is decided by the setting situation of connection steel bars and its coordinated working with moment resistance capacity of floor.
