摘　　要：文章针对叠合板式混凝土剪力墙结构体系,参考国内外有关先进标准,对混凝土墙板竖向拼缝连接抗震性能进行试验研究;采用不同构造连接方式的单片剪力墙,在水平低周反复荷载作用下,研究叠合式混凝土墙板的受力、变形性能,以及与全现浇剪力墙之间的差别。研究表明,叠合式混凝土墙板的受力状态和破坏形式基本与全现浇剪力墙一致,均呈弯剪破坏;叠合板式剪力墙中,预制板与核心混凝土部分能够较好地共同工作。Concerned with the new system of concrete shear wall structure with superimposed slab and based on the related domestic and foreign advanced standards,an experimental study is conducted on the earthquake resistance performance of the vertical joint seam of concrete wall panels.Using the monolithic shearing force wall with different structural connection mode and under the level low-cycle repeated load,the stress and distortion performance of superimposed concrete wall panel is researched as well as the difference with entire cast-in-place shearing force wall.The experimental study indicates that the superimposed concrete wall panel＇s stress condition and destruction form are basically consistent with those of the entire cast-in-place shearing force wall,assuming the failure mode under cyclic shear.Meanwhile,in the superposition beat shearing force wall,the precast block and the core concrete part can work cooperatively.
