After the implementation of“Seismic Ground Motion Parameters Zonation Map of China”(GB183062015), the seismic fortification intensity in Jiaxing urban area has changed from six degree to seven degree.Whether a large number of old building structures can meet the seismic fortification goals is worth studying. Thispaper selects a typical masonry building in the 1980s, 1990s, and 2000s in Jiaxing urban area that has been formally designed and constructed, conducts on-site investigations to obtain structural parameters, and uses different methods to evaluate their seismic capacity. The main conclusions are as follows:the seismic resistance of the three typical masonry buildings that have been formally designed and constructed in different years issignificantly different;the masonry buildings in the 1980s and 1990s have vulnerabilities in many aspects,which can't meet the seismic fortification goal of "small earthquakes are not bad,moderate earthquakes can be repaired,and large earthquakes can't fall; the typical masonry building in 2000 s has complete structural measures and short service life,and generally has good seismic resistance. The research work in this paper provides the basis forearthquake disaster risk assessment and risk reduction in Jiaxing City.
