高层建筑等效风荷载风洞试验研究

Wind Tunnel Test of Wind Load Acting on a Tall Building

分析了某高层建筑的多通道同步测压风洞试验。利用随机振动理论计算了结构等效静力风荷载,分析了风荷载随风向的变化关系,计算了结构顶部峰值加速度响应,对居住者舒适度进行了评价。

This paper presented the analysis results of wind load acting on a tall building determined in the wind tun- nel test by synchronous multi-pressure sensing system. The equivalent static wind load was calculated based on the ran- dom vibration theory. The variation of wind load with wind direction was analyzed. The peak acceleration response at the top of the structure was calculated. The comfort of occupant was evaluated.
