摘  要:为研究预制预装修模块化箱体(简称PPVC)之间连接节点的力学性能,设计制作了一个带有水平拼缝和竖向拼缝的拼装剪力墙并对其进行压剪试验。利用ABAQUS软件对压剪试验中的剪力墙进行有限元模拟,对比试验中剪力墙的试验现象以及荷载位移曲线,证明有限元模型与试验中的墙体具有高度吻合性。以插筋直径为变量进行分析,结果表明增大插筋直径能够增加其抗剪承载力并减小上下水平墙体的滑移。In order to study the mechanical properties of the connection between the prefabricated prefinished volumetric construction(PPVC system for short),an assembled shear wall with horizontal and vertical joints was designed and manufactured to carry out compression and shear tests.The finite element simulation of the shear wall in the compression and shear tests was conducted in ABAQUS software,and compared with the test phenomena and load-displacement curves of the shear wall in the tests,it is proved that the finite element model is highly consistent with the wall in the test.The results show that increasing the diameter of the joint bar can increase its shear bearing capacity and reduce the sliding of the upper and lower horizontal walls.
