| 摘 要： | 结合某高层建筑风洞模型试验,详细分析了不同工况下结构的风致响应,对干扰效应进行了深入研究。结果表明:基底弯矩的干扰效应主要表现为遮挡效应,遮挡使峰值弯矩减小,但是干扰位于侧风向或者下风向时,有可能使结构的峰值弯矩增大。受扰后,基底弯矩背景分量的变化规律与平均分量较为类似,共振分量的变化规律不明显。峰值加速度受扰后的变化也没有规律性。

| Abstract: | Based on the wind tunnel test of a tall building,wind induced response was analyzed in detail in different conditions,and the interference effects were also discussed.The results show that the interference effect of the base moment is mainly shielding effects.The base moment will be decreased when the building is shielded,but the base moment may be increased when the disturbance are located on the side wind or down wind.When disturbed,the change of background components is similar to the mean components,but... |
