摘　　要：玻化微珠永久性保温墙模复合剪力墙体系是适应我国在住宅建筑中大力开展建筑节能、发展绿色建材、推进墙体革新的新形势而提出的新型建筑节能结构体系。运用ABAQUAS有限元程序对基于玻化微珠永久性保温墙模的带缝剪力墙体系进行非线性分析,研究带缝剪力墙构件的抗震性能,并与普通剪力墙对比。通过建立合理的数值模型系统分析了带缝剪力墙在开裂破坏模式、应力应变特点、承载力和延性等方面的特点及规律,为此种新型体系的合理运用提供了理论依据。The composite shear wall system with permanent thermal-insulation wall form of glazed hollow bead is a new kind of energy-saving building,which was proposed for the request of carrying out the building energy conservation,developing the green building materials and promoting the wall material renovation in the residential building in China.In this paper the finite element analysis software ABAQUS was used to analyze the nonlinear characteristics of the structure-slitted shear wall structure with heat preservation formwork,the slitted wall were compared with common shear wall structure on the earthquake resistant behavior.Through establishing reasonable numerical model the characteristics of slitted shear wall were analyzed,including the failure mode,the stress/strain characteristics and the stiffness degradation.Especially the results showed that the ductility property of slitted shear wall structure is enhanced and the stiffness is moderated.The conclusions can be used in putting the new structure into practice.
