摘要

摘要: 为研究预装修模块化箱体建筑体系中双皮拼装剪力墙的抗震性能,设计了4个双皮拼装剪力墙和1个现浇剪力墙,在一定轴压比下对其进行低周往复加载试验,研究灌浆料强度、插筋直径以及轴压比对其破坏形态、承载力、延性、刚度及耗能的影响。试验结果表明:灌浆料、软索拉环、插筋能将双皮拼装剪力墙连接成整体;双皮拼装剪力墙的破坏形态与现浇墙类似,墙体形成X形交叉裂缝并且低部混凝土压碎;在同一条件下,现浇墙体与双皮拼装剪力墙的极限荷载基本相等;随着轴压比的提高,双皮拼装剪力墙体刚度随之提高。最后,对双皮拼装剪力墙的破坏机理和底部钢筋应变进行了分析。

Abstract: In order to study the seismic performances of assembled integrated double shear walls in Prefabricated Prefinished Volumetric Construcction (PPVC), four assembled integrated double shear walls and one cast-in-place shear wall were designed to be used for low-cycle reciprocating loading experiments. The effects of grouting material strength, diameters of connecting rebars and axial compression ratios on its failure pattern, bearing capacity, ductility, stiffness,energy consumption were studied. The test results showed that grouting materials, wireropes and connecting rebars could connect the prefabricated shear walls into a whole. The failure form of the assembled integrated double shear walls was similar to that of the cast-in-place wall. X-shaped cross cracks were formed and the lower part of the wall was crushed. In the same condition, the ultimate loads of the assembled integrated double shear walls were basically equal to that of the cast-in-place walls. Increasing axial compression ratios could significantly improve the stiffness of the assembled walls. Finally, the failure mechanism of the assembled walls and the strain of bottom rebars were analyzed.
