摘要
根据都江堰、绵竹、茂县、江油、彭州、成都、崇州等地震灾区共87幢多层钢筋混凝土框架结构房屋的震害资料,按房屋所在地不同的地震动峰值加速度分类,对该类房屋的震害进行了统计分析。根据统计数据,得出了框架结构房屋的抗震薄弱部位,分析了其震害原因。在此基础上,提出了若干改善框架房屋抗震性能的措施,可为今后框架结构房屋的设计和施工提供参考。
Based on the earthquake damage data of 87 multilayer reinforced concrete frame structures in disaster area, such as Dujiangyan, Mianzhu, Maoxian, Jiangyou, Pengzhou, chengdu, Chotagzhou, etc., the seismic damage was analyzed by statistical method according to the location of housing in different seismic peak acceleration. According to statistic data, the weak site of frame buildings was obtained, and the causes of the earthquake damage were analyzed. On this basis, some suggestions to reinforce the aseismatic measure were proposed, which will contribute to the design and construction of the multilayer reinforced concrete frame buildings.
