摘　　要：利用风洞试验,对天津海河教育园区体育中心一场两馆的大跨度屋盖在各种风向角下的风压分布情况进行了测试,考察了不同风速不同风向对屋盖表面风压系数的影响及对屋盖风荷载的影响。并根据风洞试验结果进行屋盖结构风振响应分析。提供可供设计参考的风压系数、风振系数等。The wind tunnel test is used to test the wind pressure distribution in various wind directions of the large span roof in Tianjin Haihe Education Park Sports Center. The effects of different wind speed and different direction on the roof surface pressure coefficient and the roof wind load are studied. Based on the wind tunnel test results,the wind vibration response analysis of the roof structure is conducted. The wind pressure factor and the wind vibration factor is provided, which can be referenced for the related design.
