基于A塔楼风洞试验数据,本文详细分析了风荷载特性与风致响应特征,得到了结构表面幕墙设计荷载、结构主体设计荷载以及结构加速度响应。结果表明:1) 周边建筑对风荷载分布影响较大,出现明显的干扰效应;2) 结构主体设计风荷载最大值发生在斜风向,如195˚和240˚。所得结果可为该塔楼风荷载设计提供依据。 Wind loads and wind responses of high-rise building are analyzed in detail, based on the wind tunnel test data of Tower-A. And then the design wind loads for curtain wall, structure subject, and wind induced acceleration response have been obtained. The results show that: 1) Significant interference effects by around buildings were found; 2) The maximum design wind loads for structure subject occurred on oblique wind direction, such as 195˚ and 240˚. The results are expected to be very useful for the wind load design of the Tower.
