| 摘 要： | 提出一种带加劲肋多腔双层钢板-混凝土组合剪力墙，并进行5个1:4模型试件的拟静力试验，研究该形式组合剪力墙在不同轴压比、剪跨比下的破坏形式、滞回性能、变形能力以及耗能能力。试验结果表明:带加劲肋多腔双层钢板-混凝土组合剪力墙抗震性能良好，5个试件的屈服位移角平均值为1/114，极限位移角平均值为1/48；增大轴压比可提高试件的承载力，但其抗震性能有所降低；减小剪跨比，试件的承载力和刚度有较大幅度提高，其抗震性能变化不明显。采用有限元软件ABAQUS建立该形式双层钢板-混凝土组合剪力墙模型并进行分析，其计算结果与试验吻合良好。

| Abstract: | A new type of composite shear wall with double steel plates and infill concrete with stiffeners was proposed. Quasi-static test on five specimens were conducted to investigate the influence of the axial force ratio and shear-span ratio on the seismic performance, including the failure mode, the hysteretic response, the deformability and energy dissipation. The results indicated that the composite shear wall with double steel plates and infill concrete with stiffeners shown good seismic performance of the specimens. The average values of the yield drift angle and ultimate drift angle for the five tests walls were 1/114 and 1/48, respectively. The bearing capacity of the specimens increased with the increase of the axial force ratio, but the seismic behavior decreased. With decreasing shear-span ratio, the bearing capacity and stiffness of the specimens rapidly increased, and the seismic performance was not significantly affected by the shear-span ratio. A finite element model was developed by using the ABAQUS software to simulate the performance of this type of composite shear wall, and the accuracy of the model was validated by comparing the calculated results with the experimental results. |
