本文通过对比时间域分析方法与等效概率分布的传统方法，研究了台风期间高层建筑的结构负载、位移、加速度及局部压力响应。结果显示，时间域方法能够更精确地捕捉特定风暴的风速和风向特征，导致对方向敏感响应的预测值增大。这表明，在热带风暴主导的区域，风向多变性的优势被削弱。

【摘要】

This paper presents the results of parallel analyses of tall building responses (structural loads, deflections, accelerations and local pressures) due to typhoon passages using a time-domain approach and a traditional analysis in which the tropical storm winds are represented by an equivalent probability distribution. The results show that the time-domain approach, which tracks the speed and wind direction signatures of particular storms, can result in larger predictions for responses which have a pronounced directional sensitivity. One consequence is that the benefits of wind directionality are reduced in regions where tropical storms are dominant.
