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。
Double-steel-concrete shear wall is a new type of vertical composite member and anti-side-force member composed of steel plate and concrete connected by shear connectors. As a new type of structure, it has the advantages of high structural strength, good seismic performance, convenient and quick construction Features. However, for this new type of structure, the design and application are mostly conducted in a specific project-specific manner, with a lack of specific normative standards. In order to study the axial force performance of double-steel-concrete shear walls, the axial compression tests of four double-steel-concrete shear walls were completed and the mechanical properties of the shear wall under axial load were analyzed. The influence of different distance-to-thickness ratio and the number of bolt on local buckling, failure mode and bearing capacity of steel plate are discussed. The experimental results show that the ratio of thickness to thickness has a great influence on the local buckling and failure modes of the wall, but the effect on the stiffness and bearing capacity is not very significant.
