摘　　要：根据Matlab强大的数值和矩阵计算能力,将建筑抗震计算理论与Matlab相结合,基于ArcGIS平台,计算了不同结构类型建筑物在不同强度地震作用下的地震剪力和抗震承载力;并根据损毁理论分析了其损毁情况,建立了建筑物属性表,形成抗震数据库;再利用ArcGIS的分析功能,制作了城市抗震专题图件,以期指导城市预防灾害。According to the powerful numerical and matrix calculation ability of Matlab, combining the anti-seismic calculation theory with Matlab, based on ArcG IS platform, we calculated the action of seismic shear and seismic bearing capacity of the different structure types of buildings in different intensity earthquake. And then, according to the damage theory, we analyzed their damage, and established the building property sheet, formed the anti-seismic database. Finally, we used the analysis function of ArcG IS to make the urban anti-seismic thematic maps, in order to guide urban disaster prevention.
