Western-style building is a main characteristic of Tianjin.Some of these buildings have seismic weak link

but less research have focused on their seismic capability.The seismic-resisting capacity of some western-style dwelling on Quanyechang Street of Tianjin was analyzed in this paper.The structural style and seismic behavior were introduced.Seismic-resisting capacity of a typical residential building was analyzed and appraised in accordance with codes and standards.It shows that the top story will be medium grade damaged when suffering small earthquake（intensity VII）.In medium earthquake of intensity VIII

the top will be heavily damaged.In strong earthquake with intensity IX

the top story will collapse.So the paper suggested that seismic strengthening should be carried out soon.The anti-seismic and reinforcement measures were given.Scientific basis and technical support for seismic strengthening were provided for westernstyle dwellings in Tianjin.
