摘要
基于韩岭美术馆风洞测压试验,对多坡复杂屋面围护结构风荷载进行分析。试验表明:韩岭美术馆多坡屋面屋脊位置体型系数与规范体型系数接近,但其他位置体型系数比规范所给出的局部体型系数小;屋脊位置均方根风压系数与双坡屋面接近,阵风系数比规范所给的阵风系数大;韩岭美术馆屋脊位置的阵风系数与规范相当,但挑檐位置的阵风系数高于规范计算结果。相关研究结果可供类似工程项目参考。
Based on the wind tunnel pressure test of Hanling Art Museum,the wind load of the complex slope roof is analyzed.The test shows that the shape coefficient of the ridge of the slope roof of Hanling Art Museum is close to value listed in the code,but the shape coefficient of other positions is smaller than the local shape coefficient given by the code.The RMS wind pressure coefficient of the ridge is close to that of the double slope roof,and the gust coefficient is larger than that given by the code.The gust coefficient at the ridge of Hanling Art Museum is the same as the value calculated according to the code,but the gust coefficient at the cornice is larger than the result obtained from the code.The results of this paper can be used as reference for similar projects.
