摘要

在汶川地震中框架填充墙结构产生了严重的震害.现行抗震设计对填充墙的考虑难以保证结构在地震下的抗震性能,对框架结构进行弹性阶段分析研究表明,考虑填充墙在弹性阶段对框架结构的刚度、内力和变形产生较大影响,填充墙平面、立面的不均匀布置对框架结构抗震不利.
lnfilled frames are damaged enormously in Wenchuan Earthquake.It is not always safe to have the effect of the infilled walls.It is necessary to research on the method to consider the effect of the infilled walls on the frames when making the seismic design of the frames.Based on the elastic analysis of the frame structures,the effects on the internal force,stiffness and deformation in the frames caused by the infilled walls especially in the earthquake,are achieved and then the measures to cope with the adverse effect of infilled walls are taken.The conclusions are as follows:it is unfavorable to the frame when the infilled walls are not evenly distributed.This paper proposes the measures to consider the infilled walls in the seismic design.
