摘要
本文参考有关文献 [1-5]和风流场数值模拟的结果 ,论述了屋盖上下表面风流动、压力脉动及风振动力响应的原理与规律 ,同时参考澳大利亚风荷载规范 [6]的规定及有关资料 ,提出了体育场主看台悬挑屋盖竖向静动力风荷载的计算方法 。
This paper discussed the principles and rules which regard on wind flowing and pressure flucturation of upper and lower surfaces of roof and dynamic responses induced by wind, based on some references and the results of our numerical modeling in wind fluid fields. Referring to Australian Wind Loads Code as well as some information, a method of vertical static and dynamic wind loading on a cantilevered grandstand roof is also presented, which can be used in design of practical structures.
