[摘要] 宁夏大剧院以剪力墙和18根型钢混凝土柱为整个结构的水平和竖向主要支承构件。由于建筑功能的特殊性，使得整个结构水平、竖向均存在较多不规则。为满足结构抗震设计的需要，进行了小震CQC计算、时程分析和大震静力弹塑性分析；为满足超长设计需要，进行了弹性板、钢屋盖的温度应力分析；为满足计算假定与实际情况的匹配要求，进行了施工阶段分析并严格规定支座固定顺序。同时对大“长细比”结构柱、大“无支长度”剪力墙进行了有针对性的概念设计处理。

Abstract: Ningxia Grand Theatre takes shear walls and 18 steel reinforced concrete columns as the horizontal and vertical main support components. Due to the particularity of the building functions, more irregularities exist horizontally and vertically for the whole structure. Calculation of minor earthquake with CQC method, time history analysis and static elastoplastic analysis of major efuthquakes have been made to meet the requirement of structural seismic design. Temperature stress analysis of elastic plate and steel roof has been made to satisfy the super-long design demand. Analysis of construction phases has been made and the abutment fixing sequence is strictly regulated in order to match the requirements of the calculation assumptions and actual situations.  Wlule, pertinent conceptual design treatment is made to satisfy the large "slenderness-ratio" structural columns and the large "unsupported-length" shear wall.
