［摘要］广州西塔是广州双塔的西塔楼，目前为华南地区第一高楼，高宽比超过65，主塔楼结构采用钢管混凝土斜交网格外筒+钢筋混凝土内筒的筒中筒体系。由于广州为台风多发地区，风荷载为其结构设计的控制荷载，故对其抗风设计进行了详尽的介绍。通过风气候分析确定了区域风况和设计风参数，以及与风响应有关的结构参数，并通过模型风洞试验确定了大楼的等效风荷载取值，并对大楼舒适度进行了判别。

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
