中文摘要: 双钢板-混凝土剪力墙是由钢板和混凝土通过抗剪连接件连接组成的新型竖向组合构件和抗侧力构件,其作为一种新型结构具有结构强度高、抗震性能好、施工方便快捷等特点。但对于这种新型结构,设计应用多以具体工程具体研究的方式进行,缺少专用的规范标准。为研究双钢板-混凝土剪力墙的轴向受力性能,完成了4片双钢板-混凝土剪力墙的轴心受压试验,分析了剪力墙在轴心荷载作用下的受力性能和破坏形态,探讨了不同距厚比和对拉螺栓数量对钢板局部屈曲、破坏形态以及承载能力的影响规律。试验结果表明,距厚比对墙体的局部屈曲、破坏形态有较大的影响,但对刚度和承载力影响并不十分显著。
Abstract:In the design and application process of shear wall with double steel plates and filled concrete,there is no universal approach,code and specification for this new type structure.In order to study the axial mechanical behavior of this new type structure,axial compressive tests on four wall specimens were conducted.The mechanical behavior and failure modes were analyzed under axial compressive loads,and the influence of the distance to thickness ratio and the number of pull bolt on the local bucking of steel plates,failure modes and bearing capacity were investigated.The results indicated that the distance to thickness ratio has significant effect on initial buckling of steel plate and failure modes of shear wall but little effect on the stiffness and bearing capacity of walls.
