| 摘 要： | 通过实地调研“4.20”芦山7.0级地震灾区和“8.8”九寨沟7.0级地震灾区建筑物破坏情况,对灾区内框架结构、砖混结构和简易结构三种类型的建筑物震害特征进行了对比。结果表明:两次地震中相同结构类型的建筑物在同级别地震作用下其破坏程度不同,其中砖混结构和简易结构震害特征差异性较大,分析认为除地震本身作用外,灾区房屋的抗震性能不同也是造成两次地震建筑物震害特征差异较大的原因。最后提出了建议以供灾区恢复重建、农村民居安全建设等借鉴和参考。

| Abstract: | Based on the field investigation in the earthquake zone of Lushan MS7.0 Earthquake on 20th April and Jiuzhaigou MS7.0 Earthquake on 8th August,the paper compared the seismic damage characteristics of three types of buildings in the earthquake zone including frame structur,concrete structure and simple structure.The results show that in the two earthquakes,the degree of damage under the same magnitude earthquake to the same type of building structure is different,there is a large otherness between concrete structure and simple structure damage characteristic.The analysis shows that in addition to the earthquake itself,difference of seismic performance of the building in the earthquake zone is also a reason which caused the large difference of seismic damage characteristics of buildings in these two earthquakes.Finally,some suggestions are put forward for the reference of restoration and reconstruction,the earthquake safety project of rural buildings etc. |
