摘　　要：为研究墙身竖向混合布筋的灌芯装配式混凝土剪力墙的抗震性能,设计并足尺制作了1个现浇混凝土剪力墙试件和2个预制剪力墙试件。两个预制试件的墙身分别采用竖向对称布筋和竖向混合布筋的方式,按轴压比0.3进行低周反复荷载试验。试验结果表明:混合布筋的剪力墙试件和对称布筋的剪力墙试件的破坏形态相似,均发生压弯破坏;预制构件和灌芯混凝土之间无明显的滑移现象;对称布筋的剪力墙试件的抗震性能略高于混合布筋的剪力墙试件;墙身竖向混合布筋的灌芯装配式混凝土剪力墙满足GB 50011—2010《建筑抗震设计规范》的要求。In order to study the seismic performance of core grouted congruent concrete prefabricated shear walls with vertical mixed reinforcement on the wall,1 cast-in-place concrete shear wall specimen and 2 core grouted congruent concrete prefabricated shear walls were designed and full-scale fabricated.The walls of the two prefabricated specimens adopted the method of vertical symmetrical reinforcement and vertical mixed reinforcement respectively,quasi-static tests were conducted according to the axial compression ratio of 0.3.The test results showed that the failure patterns of the shear wall specimens with mixed reinforcement and the shear wall specimens with symmetrical reinforcement were similar,and both had compression and bending failure;there was no obvious slip phenomenon between the prefabricated member and the core grouted concrete;the seismic performance of shear wall specimens with symmetrical reinforcement was slightly higher than that of shear wall specimens with mixed reinforcement;the core grouted congruent concrete prefabricated shear walls with vertical mixed reinforcement on the wall could meet the requirements of Code for Seismic Design of Buildings(GB 50011—2010).
