［提要］ 特多國家藝術(shù)中心為一涉外工程，其鋼屋蓋部分空間體形十分復(fù)雜。鋼屋蓋的主要承重和抗側(cè)力體系為懸鏈線拱，拱腳均為鉸接。設(shè)計時，荷載取值以我國規(guī)范為主，并參考國際規(guī)范。風(fēng)荷載由風(fēng)洞試驗確定，并嘗試使用風(fēng)壓時程結(jié)果直接用于結(jié)構(gòu)設(shè)計，而非常規(guī)的等效靜力風(fēng)荷載法計算風(fēng)荷載。

Structural Design of Steel Roof in National Modern Art Performance Center of Trinidad and Tobago/Jiang Wenwei, Bao Lianjin, Huang Yongqiang, Chen Jianxing (East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002,China)
Abstract:The spatial shape of steel roof in the modern art performance center of Trinidad and Tobago is very complicated. Catenary archs are the main systems to support the vertical loads and resist lateral forces. In structural design, loads and load combinations are mainly in accordance with Chinese codes, with reference to international codes such as UBC97. The distribution of wind pressure on the roof is determined by wind tunnel test for its complicated spatial shape.
Keywords:modern art performance center; Trinidad and Tobago; steel roof; UBC97; wind tunnel test; catenary arch
