摘　　要：砌体结构是历次地震中破坏较为严重的一种结构形式,为了探究不同结构布置对砌体结构抗震性能的影响,本文选取了汶川地震极震区北川县交通局三栋震害不同的砖混砌体住宅进行了震害分析。在详细考察震害遗址的基础上总结了三栋砖混房屋的震害现象,采用ABAQUS有限元分析软件,分别对北川县交通局砖混结构A、B、E栋建模,进行了弹塑性地震反应分析,综合震害考察与计算结果,分析了三栋砌体结构房屋震害不同的原因主要是墙体布置不同和承载能力储备不同。Masonry structure is usually damaged seriously in earthquake.To study the influence of different structure layout on the seismic performance of masonry structure,3 masonry buildings located in Beichuan transportation bureau which were damaged differently under Wenchuan earthquake are analyzed.Based on the detailed investigation of the earthquake site,the earthquake damage phenomenons of the 3 masonry buildings are summarized,three models of masonry building A,B and E in Beichuan transportation bureau are built with ABAQUS finite element analysis software.And elastic-plastic seismic response analysis is carried out.Considering seismic damage investigation and numerical simulation results,it is concluded that the main reasons of different damages of the three masonry buildings are the different wall layout and the different strength capacity.
