| 摘 要： | 依据汶川地震中都江堰市2000余栋建筑的震害调研结果,综合考虑结构类型、设计规范体系和性能退化等影响结构抗震能力的因素,对该市多龄期建筑的震害特征进行了统计分析.在统计都江堰市建筑构成情况的前提下,对不同结构类型、不同用途和不同建成年代建筑的震害特征进行了分析,并引入平均震害指数着重研究结构形式及龄期对结构抗震能力的影响.研究结果表明,2000年后多层砌体结构抗震性能显著提高;由于非结构构件抗震性能影响,2000年后框架结构震害大于多层砌体和底框结构.研究可为评估城市不同龄期建筑的抗震能力以及了解城市整体的抗震设防水平提供依据. |
| 关 键 词： | 多龄期建筑 震害特征 汶川地震 都江堰 抗震能力 |
