摘要 提出一种设置C形连接件的新型双钢板-混凝土组合剪力墙。为研究此类组合墙的抗震性能,设计并完成了6片高剪跨比双钢板-混凝土组合剪力墙的低周反复水平荷载试验。对试件的破坏现象、承载能力、轴压比、滞回曲线、骨架曲线、变形能力、位移延性系数及耗能能力进行了分析研究。试验结果表明:C形连接件可以有效地限制两侧钢面板的屈曲;在屈服阶段,试件的屈曲主要出现在端柱底部和墙身底部。试件的最终破坏形态为端柱脚部断裂;结构具有较高的承载力。组合墙正截面压弯承载力理论计算值与试验值吻合良好;试件的滞回曲线饱满,具有良好的延性及耗能能力,试件破坏时的平均极限位移角为1/52,位移延性系数为2.49~3.55。 The paper proposed a new-type of the double steel plates and concrete composite shear wall with C-shaped connectors. In order to study the seismic behavior of the structure, quasi-static loading tests were conducted on two double steel plates and concrete composite shear walls with large depth-span ratio. The failure phenomenon, bearing capacity, axial compression ratio, hysteresis curve, skeleton curve, deformation performance, displacement ductility factor and energy dissipation capacity were studied. The results showed that the C-shaped connectors could effectively limit the buckling of steel plate on two sides, in the yield stage, the buckling of the specimen mainly appeared at the foot of the end column and the bottom of the wall. The final damage of the specimen was mainly due to the crack of the foot of the end column. The structure showed a good bearing capacity, and the calculated results of bending bearing capacity of composite wall were compared with the test results. The hysteresis curves were full, with good ductility and dissipation capacity. The ultimate drift ratio of the specimen was 1/52, and the displacement ductility factor was between 2.49 and 3.55.
