盧云軍，周皓，焦儉（浙江省建筑設(shè)計(jì)研究院，杭州 310006）［摘要］新疆和田影劇院平面造型宛如一朵含苞欲放玫瑰花，平面形狀不規(guī)整。觀眾廳為跨度約30m，高度約為17～20m的大空間；主舞臺為寬度20m，層高28.3m的大空間；觀眾門廳中空部分為直徑18m，層高17m的圓形空間。由于結(jié)構(gòu)空曠，跨度大，樓層錯落不齊，平面形狀不規(guī)則造成柱網(wǎng)不整齊，樓座看臺懸挑較大，給結(jié)構(gòu)設(shè)計(jì)造成一定難度。結(jié)構(gòu)設(shè)計(jì)時利用樓梯間和建筑隔墻設(shè)置鋼筋混凝土剪力墻，增大結(jié)構(gòu)抗側(cè)剛度和扭轉(zhuǎn)剛度，增強(qiáng)結(jié)構(gòu)抗震能力。屋頂大跨梁施加預(yù)應(yīng)力以減少梁的擾度和裂縫寬度。樓座挑臺采用較經(jīng)濟(jì)的懸挑剛架方案。人流密集區(qū)域周邊豎向構(gòu)件采用中震彈性設(shè)計(jì)，使其擁有更高的抗震性能。［關(guān)鍵詞］和田；影劇院；空曠結(jié)構(gòu)；大跨度結(jié)構(gòu)；樓座挑臺設(shè)計(jì)；中震彈性中圖分類號：TU 318-82文獻(xiàn)標(biāo)識碼：A文章編號：1002-848X(2012)08-0038-04Structural design of -Hetian Theatre in-Xinjiang Uygur Auto. RegionLu Yunjun, Zhou Hao, Jiao Jian( Zhejiang Province Institute of Architectural Design and Reseach, Hangzhou 310006, China)Abstract: Plane modeling of Hetian Theatre in the Xinjiang Uygur Auto. Region like a rose, its flat shape is irregular. The auditorium is a large space which span is about 30m and the height of about 17～20m. The main stage is a large space which width is about 20m and the height of 28.3m. The hollow portion of the audience hall is a circular space which diameter is 18m and the height of 17m. For improving seismic capacity, the reinforced concrete shear wall is setup in the position of stairwell and the building wall to increase the lateral stiffness and torsional stiffness. By applying prestress technology to the large span roof beams reduce deflection and crack width of the beams. For the overhang seats design, the structure was deisgned with more economical cantilever frame structure. To improve the seismic performance of vertical component in the areas of population center, elastic design is chosen under intermediate earthquake.Keywords: Hetian Theatre; spacious structure;long-span structure; overhang seats design;medium earthquake elasticity作者簡介：盧云軍，碩士，工程師，Email：carl.loo@qq.com。參考文獻(xiàn)［1］GB 50223—2008建筑工程抗震設(shè)防分類標(biāo)準(zhǔn)［S］.北京：中國建筑工業(yè)出版社,2010.［2］GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范［S］.北京：中國建筑工業(yè)出版社,2010.［3］周穎，呂西林.中震彈性設(shè)計(jì)與中震不屈服設(shè)計(jì)的理解及實(shí)施［J］.結(jié)構(gòu)工程師,2008,24(6):1-5.［4］中國建筑科學(xué)研究院.多層及高層建筑結(jié)構(gòu)彈塑性靜力、動力分析軟件PUSH＆EPDA用戶手冊及技術(shù)條件［M］.
