Abstract：Upgrading the overall level of earthquake resistance of rural buildings is the key to disaster prevention and mitigation.Lushan County,Ya'an City,Sichuan Province,is located in an earthquake-prone area with high seismic risk.In order to grasp the current status of the seismic capacity of rural buildings in Lushan County,this paper carried out a sample survey of rural buildings in 8 townships and 14 villages in Lushan County,so as to count the proportions and characteristics of buildings of different structural types and identify the weaknesses of rural buildings in seismic design and construction.On this basis,the paper used the RISK-UE susceptibility index method to estimate the possible seismic damage of rural buildings under different seismic intensities and proposed targeted recommendations for improving the seismic resilience of buildings.The results show that the study area as a whole exhibits slight to moderate seismic damage under seismic intensity VII.Among them,Hexi Village,Kuaile Village,and Hebian Village,which have a smaller proportion of fortified brick-concrete houses,may experience more severe seismic damage compared to other villages.The results of the study provide a scientific basis for the seismic reinforcement and disaster prevention and mitigation of rural buildings in Lushan County.
