（中联筑境建筑设计有限公司， 杭州 310014）［摘要］宁夏大剧院以剪力墙和18根型钢混凝土柱作为整个结构的竖向主要支承构件和抗水平力构件。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，工程考虑了小震CQC法计算、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”框架柱、大“无支长度”剪力墙进行了有针对性的概念设计处理。［关键词］宁夏大剧院； 型钢混凝土柱； 静力弹塑性分析； 超长混凝土结构； 长细比； 概念设计中图分类号：TU398+.2,TU391 文献标识码：A 文章编号：1002-848X(2013)18-0008-06Structural design of Ningxia Grand TheaterYang Xuchen， Zhu Shandong, Huang Jianlin（China United Zhujing Architecture Design Co., Ltd., Hangzhou 310014, China）Abstract: Ningxia Grand Theatre takes shear walls and 18 steel reinforced concrete columns as the vertical main support components which can also resist the horizontal force. Due to the particularity of the building functions, more irregularities exist horizontally and vertically for the whole structure. Calculations of minor earthquake with CQC method, time history analysis and Pusover analysis of rare earthquakes were made to meet the requirements of structural seismic design. Temperature stress analysis of elastic plate and steel roof was made to satisfy the super-long design demands. Analysis of construction phases was made and the abutment fixing sequence was strictly regulated in order to match the requirements of the calculation assumptions and actual situations. While, pertinent conceptual design treatment was made to satisfy the large “slenderness-ratio” frame columns and the large “unsupported-length” shear wall.Keywords: Ningxia Grand Theatre; steel reinforced concrete column; Pushover analysis; superlong concrete structure; slenderness ratio; conceptual design作者简介：杨旭晨，高级工程师，一级注册结构工程师，Email：Xuchen_yang@acctn.com。参考文献［1］陈岱林, 赵兵,刘民易.
