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 new type of thermal insulation load-bearing structural system-vitrified bead insulation wall die-shear wall system is researched. The finite element software ANSYS is used to establish the simulation model of the structural system, and the structural seismic resistance analysis is carried out. Compared with the common shear wall structure Compared. The natural frequencies and modes of the two structures were determined by modal analysis. The elastic deformation was calculated by time history analysis and the failure mode of the structure was found. The simulation results show that the existence of vertical slits reduces the stiffness and self-weight of the structure, and the vibration frequency decreases with the earthquake. Therefore, the seismic effect of the structure is reduced. The actual seismic wave and artificial wave analysis show that the elastic interlayer Displacement angle and apex displacement are small, the structure has a greater lateral rigidity, strong seismic capacity.
