摘要
为了满足造型和功能需要,体育场的罩棚倾角常常根据具体条件而变化,罩棚上扬、下俯均有所应用.通常罩棚与看台顶部留有环通的空隙,有利于场内通风,但也有一些场馆未留空隙.特殊的体型将对罩棚的风荷载产生影响,本文针对罩棚倾角变化和连接开缝情况两种因素对罩棚表面风压分布的影响进行了CFD数值模拟,给出了风压系数的变化规律,并与风洞试验结果进行了比较.
Both upward angle and downward angle are very common for stadium roofs.A gap is often assigned between the roof and the stand for ventilation to the court,but some new stadiums closed this gap.Special shape has important influence on roof wind load distribution.This paper focuses on two shape factors,which are change of roof angle and joint gap between roof and stand.Computational Fluid Dynamics（CFD） method is carried out to simulate wind loads acting on the stadiums with different roof angles,with or without joint gap.The features of wind distribution are obtained and compared with the results obtaind by wind tunnel test.
