摘要
宁夏大剧院为平面不规则和竖向不规则的复杂建筑结构,本文阐述了宁夏大剧院的结构设计思路。通过对结构进行弹性分析,发现该整体结构均处于弹性状态;对结构进行弹塑性分析,发现结构在罕遇地震作用下的薄弱环节和薄弱部位,并对其进行针对性的结构加强;进而满足抗震规范规定的"三水准"、"两阶段设计"。
Ningxia theater is one of the complex structures for irregular plane and vertical irregular,this paper expounds the structural design concept of Ningxia grand theater. Based on the structure of the elastic analysis,this paper found that the overall structure is in elastic state; based on the structure of the elastic and plastic analysis,this paper found that the structure under seldomly occurred earthquake weak links and weak position,and carries on the targeted structure strengthening; seismic code provisions to meet the'three level'and'the two stage design'.
