甘肅省大劇院超限復(fù)雜結(jié)構(gòu)抗震設(shè)計梁淑萍1，莫庸2，金建民2，王從容1(1 上海建筑設(shè)計研究院有限公司，上海 200041； 2 甘肅省建設(shè)科技專家委員會，蘭州 730000)［摘要］甘肅省大劇院兼會議中心工程平面選型復(fù)雜，出現(xiàn)局部樓層錯層、樓板開大洞、豎向構(gòu)件局部轉(zhuǎn)換等，屬于特別復(fù)雜的高層建筑結(jié)構(gòu)，給結(jié)構(gòu)設(shè)計帶來了很多新的課題和理念。結(jié)合抗震規(guī)范的要求，采用三水準、兩階段設(shè)計方法，對主體結(jié)構(gòu)進行了詳細的彈性和彈塑性抗震分析。分析結(jié)果表明，在地震作用下，主體結(jié)構(gòu)具備較好的承載和變形能力，能夠達到小震彈性、中震可修、大震不倒的性能指標。通過罕遇地震作用下的彈塑性分析計算，找出了結(jié)構(gòu)潛在的抗震薄弱部位和薄弱構(gòu)件，并提出相應(yīng)的抗震加強措施，為工程設(shè)計提供了參考。［關(guān)鍵詞］ 超限復(fù)雜結(jié)構(gòu);抗震性能分析;彈塑性分析;抗震加強措施中圖分類號：TU318，TU352.1文獻標識碼：A文章編號：1002-848X(2011)01-0045-05Seismic design on ultra limit complicated structure of Gansu Grand TheatreLiang Shuping1, Mo Yong2, Jin Jianmin2, Wang Congrong1(1 Shanghai Institute of Architectural Design Research Co., Ltd., Shanghai 200041, China;2 Gansu Architecture Design & Consultation Co., Ltd., Lanzhou 730000, China)Abstract:Gansu Grand Theatre is a complex engineering, and partial split-level floors，the bigger ratio of hole on the floor and local transfer of vertical components etc are existed in the structure. This structure belongs to the special complicated and high-rise structure, which brings a lot of new issues and concepts for structure design. Combined with the requirements of the national anti-seismic norms, the elastic and elastic-plastic seismic analyses of the structure were carried out using the method of three levels and two stages. The analysis results indicate that under the earthquake, the main structure has good bearing and deformation ability，and it can reach the aims of elasticity under small earthquake，restoration under medium earthquake and uncollapsing under large earthquake. By the analysis of elastic-plastic under large earthquake, the weak parts in seismic performance were found, and the seismic strengthening measures were suggested.Keywords:ultra limit complicated structure; seismic performance; elastic-plastic analysis; seismic strengthening measure作者簡介：梁淑萍，高級工程師，一級注冊結(jié)構(gòu)工程師，Email：Liangsp@siadr.com.cn。參考文獻［1］GB50011—2001建筑抗震設(shè)計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2001.［2］DB62/T25-3037—2006蘭州市區(qū)建筑抗震設(shè)計規(guī)程(試行)［S］.［3］JGJ3—2002高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］.北京：中國建筑工業(yè)出版社，2002.［4］黃吉峰，楊志勇，邵弘，等.結(jié)構(gòu)靜力彈塑性分析PUSHOVER分析程序EPSA［C］//重慶：第十八屆全國建筑結(jié)構(gòu)學(xué)術(shù)會議論文集，2004.
