摘要
甘肃省大剧院兼会议中心工程平面选型复杂,出现局部楼层错层、楼板开大洞、局部竖向构件局部转换等,属于特别复杂的高层建筑结构,给结构设计带来了很多新的课题和理念.结合国家抗震规范的要求,对该工程主体结构进行了罕遇地震作用下的弹塑性计算分析,并对工程结构抗震性能进行了分析和综合评价,通过弹塑性分析计算,找出结构潜在的抗震薄弱部位和薄弱构件,并提出相应抗震加强措施,为同类工程设计提供了有价值的参考数据.
Gausu Grand Theater have with the complex architectural design, Some of adverse factors, such as partial split-level floors,the bigger ratio of hole on the floor and local transfer of vertical components etc are existed in the engineering structure. This building belong to a special complicated and high-rise structure, it bring a lot of new issues and concept for structure design. Combined with the requirements of the national anti-seismic norms, the method of elastoplastic analysis was used on the structure under the scarce earthquake, and evaluated the seismic performance of whole structure. By the analysis of static elastic-plastic, the weak part in seismic performance were found and the seismic strengthening measure were suggested that can be a reference for similar projects design.
