温带气候条件下高层建筑抗风设计方法的研究综述
|
摘要
风气候中风向角对结构风荷载和风致响应是非常重要的一个影响因素,高层建筑每个风向区间受到的风荷载和产生的风致响应是并不相同的。介绍了温带气候条件下,国内外各种考虑了风向角影响后高层建筑抗风设计主要的研究方法,包括最不利工况法、逐个风向区间法及穿越法,并指出了它们的优缺点及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,which are different in high-rise buildings under each wind direction. The main research methods for wind resistance design of high-rise buildings are introduced under the conditions of temperate climate,including the most unfavorable working condition method,one by one wind direction interval method and the crossing method. Their advantages,disadvantages and further research to study had been pointed out. That will provide reference for the wind resistance design of high-rise buildings.
