建立了2008年汶川地震建筑物倒塌比(CRS)与强震特征之间的关系。建立了与PGA、PGV、PSA和PPSV相关的建筑物易损性函数。CR50%的破坏标准为PGA>；600GAL，PGV>；55厘米/S，PSA>；2200GAL，PPSV>；120厘米/S。汶川地震的震害比1995年神户地震和1999年集集地震的相同水平的地面运动更严重。
Relationships between collapse ratios (CRs) of buildings and characteristics of strong ground motions during the 2008 Wenchuan earthquake was founded. Vulnerability functions of buildings were established in relation to PGA, PGV, PSA, and PPSv. Damage criteria for CR50%, corresponding to the “extremely serious damage” were PGA>600 gal, PGV>55 cm/s, PSA>2200 gal, and PPSv>120 cm/s. Seismic damage during the Wenchuan earthquake was heavier than that of the 1995 Kobe and 1999 Chi-Chi earthquakes for the same levels of ground motion.
