- Abstract:
-
The fragility matrix of buildings is an important calculation parameter for the initial evaluation and calculation of the direct economic loss of buildings after the earthquake.This paper analyzes the regional characteristics of Yunnan from the natural factors,social factors and ethnic customs,and Yunnan is divided three zones:Northeast,Northwest and Southwest.Based on the earthquake damage data in Yunnan Province from 1993 to 2017,used the experience analysis method and another method of making empirical earthquake damage matrix,fragility matrixes of each building structures of rural building in three regions are obtained.Based on the fragility matrix,calculated the probability of damage ratio curve and fragility index of each building structures,this paper analyzes the seismic capacity of different rural building structures and the seismic capacity of the same structure in different zones.The results show that:there are large regional differences between mud-wood structures and brick-wood structures,and the seismic capacity in Northeast Yunnan is the worst; the regional difference of seismic capacity of masonry structures and reinforced concrete structures is not obvious.
