带架空层框架阻尼填充墙结构抗震性能研究
|
摘要
为研究阻尼填充墙在带架空层框架结构中的减震效果,设计架空层位置不同的3栋阻尼填充墙框架结构及相应的带架空层普通填充墙框架结构,采用PERFORM-3D对其进行了罕遇地震下的弹塑性时程分析。分析结果表明:阻尼填充墙对结构的刚度效应小,其在结构中沿竖向不连续布置所引起的上下相邻楼层刚度突变不明显;阻尼填充墙在底层、中间层或顶层架空框架结构均可发挥较好的减震效果,能有效解决楼层架空造成结构在地震中发生薄弱层破坏的问题;阻尼填充墙可耗散输入结构的部分地震能量,减轻结构构件在地震中的破坏,起到保护主体结构的作用。
In order to investigate the seismic performance of damp infilled wall-frame structure(DIWF) with stilt floors, DIWF and conventional infilled wall frame structure(CIWF) with a stilt floor in three different locations were designed, and elasto-plastic analysis by PERFORM-3D software were carried out. The results show that: The stiff ness effect of damped infill wall(DIW) is much weaker than that of the conventional infilled wall(CIW), adjacent floor stiffness mutation caused by the DIW vertical arranged discontinuous is not obvious; DIW plays a good seismic reduction effect in frame structure with empty space and effectively solve the weak story problem; DIW can dissipate partial structural earthquake energy and reduce the damage of structural members that protect the main structure.
