[摘要] 寧夏大劇院以剪力墻和18根型鋼混凝土柱為整個(gè)結(jié)構(gòu)的水平和豎向主要支承構(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，進(jìn)行了小震CQC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”結(jié)構(gòu)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。

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.
Keywords: Ningxia Grand Theatre; steel reinforced concrete column; static elastoplastic analysis; super-long concrete structure; slendemess ratio; conceptual design
