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。
Ningxia Grand Theater with shear walls and 18 steel columns for the entire structure of the horizontal and vertical main support member. Due to the particularity of the building function, the whole structure has many irregularities in horizontal and vertical directions. In order to meet the needs of structural seismic design, small-scale CQC calculation, time-history analysis and large-scale static elasto-plastic analysis were carried out. In order to meet the long design requirements, the temperature stress analysis of elastic plate and steel roof was carried out. Assuming the matching requirements with the actual situation, the construction phase analysis was carried out and the fixing order of bearings was strictly regulated. At the same time on the “slender than” structural column, large “no branch length ” shear wall for a targeted conceptual design process.
