中文摘要：

考虑叠合板式剪力墙（SSSW）墙体截面弯曲变形、轴向变形及剪切变形对单元动力特性的影响,应用纤维模型模拟墙体弯曲与轴向变形相互作用的非线性滞回特性,通过剪切弹簧模型对剪切变形进行模拟。采用此模型对不同变幅加载路径下的4片不同配筋形式和轴压比的墙体进行数值模拟,并与拟静力试验结果进行对比。结果表明,考虑剪切变形的纤维模型可以较好地模拟SSSW的非线性特性,可以采用此模型进行SSSW结构弹塑性分析。

英文摘要：

The bending,axial and shear deformation of the superimposed slab shear wall （SSSW） affect its dynamic property.To consider this effect,the fiber model is adopted to simulate the nonlinear hysteretic interaction of bending deformation and axial deformation,and the shear deformation is modeled by the shear spring model.Numerical simulations of four SSSWs with different boundary restraints and axial compression ratios using this model are carried out under different loading patterns.The comparison between the results of cyclic test and numerical simulations demonstrates that the nonlinear behavior of the SSSW can be simulated by the fiber model considering shear deformation,and the proposed model can be applied further to the inelastic analysis of structures with such SSSW.
