Average Damage Ratio and Earthquake Damage Matrix of Non-Engineered Building in Seismogenic Provincial Regions in China

Abstract:

Non-engineered buildings are most of self-built house, which locate in rural area in China. The structural defect of non-engineered buildings could reduce seismic capacity. The damage of these buildings are the main cause of earthquakes casualties and economic losses. The main types of the building structures include the wooden house, soil and wood house, brick and wood house and masonry house. It is the seismogenic provincial regions for Xinjiang, Qinghai, Gansu and Yunnan in China. Based on the four type houses in the four regions, 104 earthquake disaster loss reports were selected from 1990 and 2013. This article focused on the analysis of house damage data. This article proposes "the average damage ratio" concept, which takes one provincial region as an area and studies the whole area data. Due to a combination of multiple and differenteffects of earthquakes within one provincial region, the average damage ratio can be on behalf of the damage ratio, and reflects the non-engineered building characteristics in the provincial region. And then the article demonstrates that the earthquake damage matrix of different house types in these four provinces area. The earthquake damage matrix provides a more reliable basis for the earthquake disaster evaluation in rural area.
