汶川地震都江堰地区建筑震害情况分析
|
摘要
结合5.12汶川大地震的震害实例分析都江堰地区建筑物的震害情况,证明规则合理的结构方案是建筑物具有良好抗震性能的首要保证;地震区的建筑应为延性结构,增强结构延性是提高建筑物抗震性能的重要措施;合适的概念设计和构造措施对提高结构的延性起着至关重要的作用。
Building conditions during the May-12 Wenchuan earthquake in Dujiangyan are analyzed according to practical earthquake disasters and it is proven that regular and rational structure is the most important factor to guarantee favorable aseismatic performance of building;buildings in seismic area shall adopt ductile structure and increasing structural ductility is an important and effective measure to improve aseismatic performance of buildings;appropriate conceptual design and construction measures play important roles in increasing structural ductility.
