摘要

继2008年汶川8.0级特大地震后,2013年4月20日8点02分在四川省雅安市芦山县又发生了7.0级强烈地震,震源深度13公里,造成大量房屋严重破坏或倒塌。根据不同的结构类型、不同烈度区,文中对应急调查评估的603栋各类房屋结构进行了详细的统计归纳总结,得到了各类结构在不同烈度下的破坏比。在此基础上,主要对钢筋混凝土结构、砌体结构、砖木结构和木结构的震害特征进行了深入剖析,此外还对一栋大跨空间结构和一栋隔震结构的破坏特征进行了分析,最后针对各类结构在地震中尚存在的主要问题,提出了一些改进建议。
Following 8.0 Wenchuan strong earthquake in 2008,Lushan 7.0 earthquake has occurred at 8: 02 on April 20,2013,with a focal depth of 13 km.A large number of houses weve severely damaged or collapsed in this earthquake.According to different types of structures and different intensity zones,the damage to 603 building structures,which are investigated after the earthquake is summarized,and the structural damage ratios of all kinds of structures are got under different intensity.On this basis,seismic damage characteristics of reinforced concrete structure,masonry structure,wood frame structure and brick-wood structure are analyzed thoroughly.Moreover,seismic hazard characteristics of a large-space structure and an isolated structure are also analyzed.Finally,some suggestions to improve the design and construction are provided.
