摘要
目的为了更好地满足建筑工业化的要求,同时解决预制墙体的尺寸受运输及吊装等因素限制等问题,提出利用暗柱水平拼接两片墙板形成整体剪力墙,并对其进行抗震性能试验研究。方法对带暗柱拼缝的单面叠合式剪力墙和整体单面叠合式剪力墙进行拟静力试验,以有无暗柱拼缝作为变化参数,对比分析两种新型构件的破坏模式、滞回性能、延性性能以及耗能能力等抗震性能指标;并通过非线性有限元软件ABAQUS模拟进行分析。结果带暗柱拼缝的单面叠合式剪力墙与同几何尺寸的整体单面叠合式剪力墙破坏形式基本一致,均呈弯剪破坏;滞回性能、延性性能以及耗能能力等抗震性能指标相似;两种构件的有限元模拟分析与试验结果吻合较好。结论带暗柱拼缝的单面叠合式剪力墙抗震性能与整体单面叠合式剪力墙基本一致,可用于装配式混凝土剪力墙结构体系。
In order to satisfy the requirements of building industrialization better,at the same time,to solve the problem that the size of the prefabricated wall is restricted by factors such as transportation and hoisting,this paper proposes using the concealed column to connect the two single-faced superposed shear walls horizontally,and get experimental study on its seismic behaviour.This paper carried out pseudo-static tests on single-faced superposed shear wall with concealed column joints and integral single-faced superposed shear wall.By setting the concealed column joint as the variation parameter,the seismic behaviour indexes such as failure mode,hysteretic performance,ductility performance,stiffness degradation,energy dissipation capacity of the two new types of structures were compared and analyzed.Then the nonlinear finite element software ABAQUS was used to verify the results.The failure mode of single-faced superposed shear wall with concealed column joints is basically the same as the integral single-faced superposed shear wall with the same geometric size.Both of them are bending-shear failure modes,and have similar seismic behaviour indexes.The finite element analysis is consistent with the experimental results as well.The seismic behaviour of the single-faced superposed shear wall with concealed column joints is basically the same as the integral single-faced superposed shear wall.The single-faced superposed shear wall with concealed column joints can be used in the prefabricated concrete shear wall structure system.
