摘 要: 按通常的方法将高层建筑顺风向风荷载及风致响应分解为平均、背景和共振三部分。在合理简化的基础上提出了形式简单、与响应类型无关的背景和共振等效风荷载和响应的简化计算公式。两个典型数值算例的计算表明,该法精度很高,是一种很好的实用计算方法。 In this paper, the along-wind loads and wind-induced responses of high-rise buildings are decomposed into mean, background and resonant components. The distribution of background component is same as that of mean component in the inertial force model when calculating the resonant component. Simplified formulas foralong-wind equivalent wind loads and wind-induced responses are presented, which are independent of type of response. Two typical engineering examples are studied to verify the present method.
