Integrated disaster matrix and vulnerability index analyze the seismic performance of typical structures in rural villages in historical earthquakes

This study investigated and classified typical structures in rural village and analyzed the vulnerability. Based on the statistics of earthquake damages with magnitudes above 5 from 1996 to 2013 in China, the damage matrixes of types of structures in rural village are obtained. The vulnerability index and equation of structure are crucial to assess the earthquake losses of typical structures under different magnitudes earthquakes. According to the seismic loss of different types of structures under different earthquake magnitudes, there are possible to improve the seismic resilience of the buildings in rural village. Moreover, the regional vulnerability is analyzed by β probability distribution function. The comprehensive seismic vulnerability index of different types of structures in rural villages is obtained. The main research is to predict the loss of different types of structures under different earthquake magnitudes in the future, and to provide technical support for types of buildings in rural village reinforcement.
