基于Reynolds时均N—S方程和SST模型,对一低层双坡门式刚架结构的表面风压进行CFD数值模拟,并将模拟结果与风洞试验结果进行比较.根据模拟结果对门式刚架结构各表面的风压分布特性进行了分析和归纳,可为该类建筑的抗风设计提供参考.
Based on the Reynolds averaged N-S equations and SST turbulence model, the wind-induced pres- sures on a portal framed structure was predicted by CFD simulation . The computation results were compared with the wind tunnel test results. The distribution characteristics of the wind pressure were analyzed and conclu- ded on the basis of numerical results, which provide reference for the wind-resistance design of this type of por- tal framed structures.
