- Abstract:
-
Fifty-six destructive earthquakes occurred in Yunnan from 1992 to 2005,and abundant disaster data accumulated.Post-earthquake Field Works—Part 4:Assessment of Direct Loss came into effect on October 2005,and the class of simple-buildings was put forward in this standard.Thus,the former five damage classes of simple-buildings have been simplified to three classes.In this paper,we calcalate the damage ratio in different seismic regions of 56 earthquakes and do a weighted average of the former seismic damage indexes using the damage ratio.In this way the seismic damage indexes of three damage classes are gained.
