［摘要］廣州西塔是廣州雙塔的西塔樓，目前為華南地區(qū)第一高樓，高寬比超過65，主塔樓結構采用鋼管混凝土斜交網(wǎng)格外筒+鋼筋混凝土內(nèi)筒的筒中筒體系。由于廣州為臺風多發(fā)地區(qū)，風荷載為其結構設計的控制荷載，故對其抗風設計進行了詳盡的介紹。通過風氣候分析確定了區(qū)域風況和設計風參數(shù)，以及與風響應有關的結構參數(shù)，并通過模型風洞試驗確定了大樓的等效風荷載取值，并對大樓舒適度進行了判別。
［關鍵詞］超高層建筑；設計風荷載；風氣候分析；風洞試驗；阻尼比

Abstract:Guangzhou West-tower is the west tower of Guangzhou Twin Towers.Now it is-the tallest building in South China,and its ratio of height and width is beyond 6.5. The structure system is tube-in-tube system with CFT diagrid outside and reinforced concrete core inside. Guangzhou is a typhoon climate region,wind loads will be the controlling load when designing the structure of West-tower, so study on wind-resistance design is detail introduced.The wind condition of local region and wind profile by wind climate analysis are defined,the parameters affecting the reaction of building against wind loads are chosen, and the equivalent static wind loads and acceleration of the peak of the building are gained by wind tunnel tests.
Keywords:super-tall building; design wind loads; wind climate analysis; wind tunnel tests; damping ratio
