Abstract: Establishing empirical seismic fragility curves based on massive seismic damage data from historical earthquakesis an important part of earthquake prevention and disaster reduction work in China. Combined with a considerable amount ofliterature, the research progress on empirical seismic fragility curves and relevant codes or standards at home and abroadwere systematically sorted out, and the shortcomings of each link in the establishment of the empirical seismic fragilitycurves,such as buildings classification, damage states division, selection of ground motion parameters, and curves fitting,ect. were analyzed. Combined with modern disaster investigation methods, suggestions for optimizing and expandingseismic damage data, selecting ground motion parameters reasonably, and standardizing the establishment procedures ofempirical seismic fragility curves were put forward.

Keywords:house building; empirical seismic fragility curve; earthquake prevention and disaster reduction; damage state;ground motion parameter
