热带风气候条件下风荷载研究的风暴路径法

Storm passage method of wind load study in tropical wind climate

风气候中风向角对结构风荷载和风振响应是非常重要的一个影响因素,在热带气候条件(如台风)下风向角随时间变化较快,作用在建筑物上的风荷载是非平稳随机过程,这导致了其抗风设计方法与季风的不同。详细的介绍了在考虑风向角的影响后,能用于热带气候条件的风暴路径方法。该方法用等效静力风荷载思想计算用于承载力极限状态设计的风荷载。并且提出了还需要进一步研究的问题,为高层建筑抗风设计研究提供参考。

Wind direction has some significant effects on wind loads and wind-induced responses. Wind direction varies quickly within a particular time in tropical wind climates. And wind load on building is a non-stationary random process, which leads to the building＇ s wind-resistant design methods being different from the extra-tropical wind climates, the storm passage method has been introduced detailed which can be used to design in tropical wind climates. The theory of equivalent static wind loads is applied to calculate the wind loads in this method. It also includes some contents about further research being done on the subject. Also, it provides reference for the study of wind-resistant design of high-rise
