陳彬磊，郭宇飛，張勇（北京市建筑設計研究院有限公司， 北京 100045）［摘要］作為第26屆世界大學生運動會的開幕式體育場，深圳灣體育中心在設計之初，便因其方案的新穎奇特，備受關注。體育中心屋蓋部分采用了“建筑結(jié)構一體化”的設計手法以及“一場兩館一體化”的設計理念，建筑的復雜曲面造型和緊湊化的設計決定了結(jié)構的復雜性。體育中心鋼結(jié)構屋蓋為超大跨度空間結(jié)構，平面尺度約530m×240m，由單層網(wǎng)殼、雙層曲面網(wǎng)架及豎向支撐系統(tǒng)構成。單層網(wǎng)殼為復雜的空間曲面網(wǎng)格結(jié)構，采用箱形彎扭構件編織而成的四邊形網(wǎng)格構成。豎向支撐系統(tǒng)包括支撐網(wǎng)殼的31棵樹形柱、支撐網(wǎng)架的V形柱、觀景橋立柱和下沉廣場西立面幕墻柱。介紹了鋼結(jié)構屋蓋的結(jié)構體系組成特點，回顧了屋蓋鋼結(jié)構方案設計的全過程。［關鍵詞］單層網(wǎng)殼； 樹形柱； 彎扭構件； 網(wǎng)架； 方案設計中圖分類號：TU356；TU393.3 文獻標識碼：A 文章編號：1002-848X(2013)17-0063-05Schematic design of steel structure for Shenzhen Bay Sports CenterChen Binlei, Guo Yufei, Zhang Yong(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: As the opening ceremony site of 26th universiade, Shenzhen Bay Sports Center attracts much attention from the beginning of design, because of its novel scheme. The sports center roof is designed by using the concepts of "integration of archirecture and structure" and "integration of stadium, gymnasium and natatorium", which made a compact design. And the complex roof surface results in the difficulties of structural design. As a super-long span spatial structure, the steel roof structure of Shenzhen Bay Sports Center is composed of single-layer latticed shell, two space grid structures and vertical support system. The single-layer latticed shell is a complex spatial surface, which meshed by quadrilateral grids with crooked-torsional box-section members. Vertical support system includes 31 dentritic columns, V-shaped columns, columns of bridge pier and latticed columns of west curtain wall. An introduction is given for the structural system of steel roof and its special features, and the entire process of scheme design is also reviewed.Keywords: Single-layer latticed shell; dentritic column; crooked-torsional member; grid structure; schematic design作者簡介：陳彬磊，教授級高工，Email：biad1s1@126.com。參考文獻［1］陳彬磊, 郭宇飛, 柯長華，等. 深圳灣體育中心鋼結(jié)構屋蓋設計及研究［J］. 建筑結(jié)構, 2011, 41(9):1-10.［2］郭宇飛, 陳彬磊, 張勇. 深圳灣體育中心鋼結(jié)構關鍵節(jié)點設計［J］. 建筑結(jié)構, 2013, 43(17)：71-74.［3］陳俊, 張其林, 謝步瀛. 樹狀柱在大跨度空間結(jié)構中的研究與應用［J］. 鋼結(jié)構, 2010, 25（3）:1-4.［4］WANG D S, GAO C, ZHANG W Y, et al.
