摘　　要：研究一种新型保温承重结构体系—玻化微珠保温墙模带缝剪力墙体系,利用有限元软件ANSYS建立该结构体系仿真模型,进行结构抗震动力分析,并与普通剪力墙结构进行了对比。采用模态分析法确定了两种结构的自振频率和振型,采用时程分析法进行弹性变形计算,找到该结构的破坏模式。仿真分析表明:竖缝的存在降低了结构刚度和自重,在地震作用下,结构振动频率减小,因此降低了结构地震作用效应;通过实际地震波和人工模拟波分析表明,该结构体系弹性层间位移角和顶点位移都很小,结构具有较大抗侧刚度,抗震能力较强。A kind of new structural system, slitted shear wall structure with heat preservation formwork by GHB （glazed hollow bead）, was presented. The seismic dynamic analysis on the building structured by slitted shear walls was conducted by using ANSYS software. Meanwhile, the common shear wall model was established to contrast with the experimental building structure model. The frequencies and vibration modes of two structures were analyzed, and the elastic deformation of the structure under the earthquake loading was calculated by using the time-history analytic method to find out the failure type of the structure. The result of simulation analysis shows that the slits could reduce the self-weight and stiffness of the structure. The frequency of this structure is less than that of a common shear wall structure, and in turn, the slits could moderate the structural reaction to earthquake. In addition, the simulation analysis on this new type of the structure under actual earthquake wave and simulated earthquake wave is presented. The results show that the elastic inter-storey drift and top displacement is very slight in the case of frequently occurred earthquake, so this new type of the structure has strong stiffness and capacity of seismic resistance.
