介绍2014年鲁甸MS6.5与景谷MS6.6地震灾区房屋概况,对两次地震灾区房屋的震害特征进行阐述,从房屋建筑材料、结构选型、场地条件等方面对比分析两次地震灾区的房屋抗震能力,进一步分析景谷灾区房屋抗震性能优于鲁甸灾区的原因,并强调抗震概念设计的重要性,提出建议以供恢复重建、农村民居地震安全工程、新农村建设等借鉴参考。

Firstly, we briefly introduced the basic situation of the buildings and the damages characteristics of the buildings in Ludian MS6.5 and Jinggu MS6.6 earthquakes disaster areas in Yunnan in 2014. Secondly, according to the building materials, structural types, site condition etc., we compared and analyzed the seismic capacity of the buildings in these two earthquakes disaster areas. Furthermore, we discussed the reason of the seismic capacity of the buildings in Jinggu MS6.6 earthquake disaster area is better than that in Ludian MS6.5 earthquake disaster area,and emphasized on the importance of seismic design. Finally,we put forward the suggestions for the reference of restoration and reconstruction, the earthquake safety project of rural buildings, New Countryside Construction etc..
