［摘要］深圳灣體育中心鋼結(jié)構(gòu)屋蓋平面約530m×240m，其單層網(wǎng)殼為復(fù)雜的空間曲面網(wǎng)格結(jié)構(gòu)，采用箱形彎扭構(gòu)件編織而成的四邊形網(wǎng)格構(gòu)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。從結(jié)構(gòu)規(guī)模、復(fù)雜和難易程度來講，在給設(shè)計帶來挑戰(zhàn)的同時，也給工程師提供了設(shè)計創(chuàng)新的可能。介紹了鋼結(jié)構(gòu)的體系組成及特點和結(jié)構(gòu)的設(shè)計創(chuàng)新內(nèi)容，包括超長結(jié)構(gòu)不設(shè)縫、彎扭構(gòu)件的可編程圖紙表達(dá)、結(jié)構(gòu)建模及設(shè)計方法的創(chuàng)新以及自主編制的質(zhì)量驗收標(biāo)準(zhǔn)，為工程的設(shè)計完成提供了保障。

Abstract: 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 is 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. Several innovative structural design aspects are elaborated, such as super long structure without temperature joints, the programmable expression of drawings for crooked-torsional members, innovative methods used for structural modeling and design, independent project standards for acceptance of construction quality and installation errors, and so on.

Keywords: super long single-layer latticed shell; temperature action; crooked-torsional member; vector; quality standard
