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 study the damping effect of the damping infill wall in the framework with overhead plies, three damping infilled wall frame structures with different overhead plenum positions and the corresponding ordinary infill wall frame structure with overhead plies were designed and PERFORM-3D Elasto - plastic time history analysis under rare earthquakes. The analysis results show that the damping effect of the infilled walls on the structure is small, and the discontinuities in the vertical discontinuity caused by the vertical discontinuities in the structure are not obvious. The damping infill walls are not obviously changed in the bottom, middle and top overhead structures Can play a better damping effect, can effectively solve the overhead caused by the structure of the weak layer damage occurred in the earthquake; damping wall can dissipate part of the seismic energy input structure, to reduce the structural components in the earthquake damage, play Protect the main structure of the role.
