高层建筑风荷载及抗风设计
|
摘要
随着轻质高强新型建筑材料的不断涌现,高层建筑不但建筑形式变化多样,而且结构体型也朝着高大、轻柔的方向发展。故风对高层建筑的影响越来越大。所以必须认真对待高层建筑中风荷载。本文通过简述风的起因、风的特征、风压及风荷载,更进一步说明了高层建筑中结构风振响应,从而达到风振控制以其实现采用非承重控制装置施加控制力抵御风振反应的设计方法。
Along with the light mass and high intensity material unceasing emergence, the high-rise construction pattern and the structure are developing towards the gentle and tall direction.Therefore the wind is more and more big to the high-rise construction influence.We must think better of the question.This article through the summary wind cause, the wind characteristic, the wind pressure and the wind load, showed the wind inspires to the high-rise construction, thus achieved the desigh method of the wind inspire control ,which use the non-load-bearing control device .
