摘　　要：本文完成了8片钢板夹心混凝土组合剪力墙面内抗震性能试验,研究了钢板夹心混凝土组合剪力墙的承载力、抗震性能及破坏模式,以及剪跨比、含钢率和栓钉间距对其性能的影响.研究表明,剪跨比1.0～1.5的所有试件破坏形态均为压弯破坏;试件滞回曲线比较饱满,极限位移角大于或接近1/100,试件的耗能能力及变形能力均较强;剪跨比小于1.5时,钢板的抗剪能力发挥充分,试件的变形能力较好;含钢率越大,抗侧承载力越高,变形能力相对强;在试验所采用的栓钉间距范围内,栓钉间距对试件承载力、变形、延性性能影响均不明显.基于叠加原理提出了钢板夹心混凝土剪力墙压弯承载力的建议公式,该公式与试验结果吻合较好,并具有适当的安全度.By quasi-static test of 8 steel-concrete-steel sandwich composite wall specimens, the bearing capacity, seismic behavior and failure mode of the specimens are studied, and the impact of the shear-span ratio, steel ratio and interval of studs on the properties of the specimens is analyzed. The observed failure modes of specimens with different shear-span ratios between 1.0 to 1.5 are all compression-bending failure. The hysteretic curves of all specimens are relatively plump, which validate the well energy dissipation capacity of the specimens. The test results show that with shear-span ratio less than 1.5, the shear property of the steel plate is well played, which ensures the well deformability of the specimens. The observed ultimate drift ratios of all specimens are greater than or close to 1/100. The bigger the steel ratio is, the better the lateral capacity and the deformability of the specimen is. Among the intervals of studs in the test, it has no significant effect on the bearing capacity, deformability and ductility of the specimens. Based on the principle of superposition, an advised formula for the compression-bending capacity of the shear wall is proposed, which fits well with the test result and had a proper safety margin.
