本文介绍了深圳机场航站楼扩建工程外墙表面及屋面风压的风洞试验结果,分析了该楼屋面风压的分布规律及几个重要的影响因素。试验结果表明:大型屋面风荷载主要集中在屋面悬挑部分,尤其是前缘处;前缘处的负压最大且变化剧烈,其值与悬挑长度、悬挑部分水平倾角、前缘外形等有关。
This paper introduces the results of wind tunnel tests on the surface and roof pressure of the external wall of Shenzhen Airport Terminal Expansion Project, and analyzes the distribution law of wind pressure on the roof of the building and several important influencing factors. The test results show that the large roof wind load is mainly concentrated in the cantilevered part of the roof, especially at the leading edge; the negative pressure at the leading edge is the largest and changes drastically; the value and the cantilever length, the horizontal dip angle of the cantilever part, the front edge shape, etc. related.
