摘　　要：运用ANSYS有限元分析程序对一种新型保温承重结构体系——保温墙模带缝剪力墙体系进行非线性分析。通过建立合理的力学模型,分析了不同剪跨比带缝剪力墙在水平荷载作用下的破坏模式、骨架曲线及刚度退化等方面的特点和规律,同时对比分析了带缝剪力墙与传统剪力墙的抗震性能。分析结果表明:开缝剪力墙刚度降低,延性增加,进而可以提供更大的变形能力,以上结论可为此种新型体系的安全设计和工作性能评价提供依据。The finite element analysis software ANSYS was used to analyze the nonlinear characteristics of a kind of new structure-slitted shear wall structure with heat preservation formwork. Based on the reasonable mechanic models, the characteristics of the different shear-span ration slitted shear wall were analyzed, including the failure mode, skeleton curve and the stiffness degradation, meanwhile, the slitted wall were compared with shear wall structure on the seismic behavior. The results showed that the stiffness of slitted shear wall structure is moderated and ductility property is enhanced, therefore, it can afford more deformation capability. The conclusions may be used in designing and evaluation of the performance for the new structure.
