【摘要】：完成了6个带竖向接缝的预制混凝土空心模剪力墙试件在恒定轴力作用下的拟静力试验,研究了墙体的受弯性能以及竖向接缝的连接性能,明晰了墙体的破坏过程和破坏形态。试验结果表明:墙体破坏形态与钢筋混凝土剪力墙相似,破坏时墙体根部混凝土压溃、边缘构件纵筋压曲;部分墙体的破坏区域发展至中部墙板,预制混凝土与后浇混凝土剥离;竖向接缝构造合理、连接可靠,能够保证墙体的整体性能,对受弯性能基本无影响;试件的转角延性系数为4.35~12.54,具有良好的延性;提高边缘构件纵筋配筋率和轴压比,墙体的承载力提高,混凝土压溃面积增大;采用单排竖向插筋对墙体的受弯性能影响较小;GB 50010—2010《混凝土结构设计规范》的计算方法可用于计算空心模剪力墙试件的承载力,计算结果较为保守。
[Abstract]:The pseudo static test with 6 vertical joints of precast concrete hollow die shear wall specimens with an invariable axial force, the flexural properties and the connection performance of vertical joints of the wall, clarifies the failure process and failure mode of the wall. The experimental results show that the failure mode of reinforced concrete shear wall with similar the concrete wall, crushing, edge member longitudinal reinforcement buckling failure; regional development to the middle part of the wall panel, precast concrete and pouring concrete peeling; vertical joint of reasonable structure, reliable connection, to ensure the overall performance of the wall, no influence on the bending performance; ductility coefficient of the test corner 4.35~12.54 has good ductility; improve the edge component of longitudinal reinforcement ratio and axial compression ratio, wall bearing capacity, concrete crushing area increases; with a single row of vertical reinforcement of the wall The smaller effect of bending performance calculation method of GB; 50010 - 2010< code for design of concrete structure "can be used to calculate the hollow shear wall model of the bearing capacity of the specimen, the results are more conservative.
