（中聯(lián)筑境建筑設(shè)計(jì)有限公司， 杭州 310014）［摘要］寧夏大劇院以剪力墻和18根型鋼混凝土柱作為整個(gè)結(jié)構(gòu)的豎向主要支承構(gòu)件和抗水平力構(gòu)件。由于建筑功能的特殊性，使得整個(gè)結(jié)構(gòu)水平、豎向均存在較多不規(guī)則。為滿(mǎn)足結(jié)構(gòu)抗震設(shè)計(jì)的需要，工程考慮了小震CQC法計(jì)算、時(shí)程分析和大震靜力彈塑性分析；為滿(mǎn)足超長(zhǎng)設(shè)計(jì)需要，進(jìn)行了彈性板、鋼屋蓋的溫度應(yīng)力分析；為滿(mǎn)足計(jì)算假定與實(shí)際情況的匹配要求，進(jìn)行了施工階段分析并嚴(yán)格規(guī)定支座固定順序。同時(shí)對(duì)大“長(zhǎng)細(xì)比”框架柱、大“無(wú)支長(zhǎng)度”剪力墻進(jìn)行了有針對(duì)性的概念設(shè)計(jì)處理。［關(guān)鍵詞］寧夏大劇院； 型鋼混凝土柱； 靜力彈塑性分析； 超長(zhǎng)混凝土結(jié)構(gòu)； 長(zhǎng)細(xì)比； 概念設(shè)計(jì)中圖分類(lèi)號(hào)：TU398+.2,TU391 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：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作者簡(jiǎn)介：楊旭晨，高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email：Xuchen_yang@acctn.com。參考文獻(xiàn)［1］陳岱林, 趙兵,劉民易.
