建筑物风荷载体型系数的数值模拟

摘要

Numerical wind tunnel method has sigwificant advantages such as low cost, fasting, collecting more comprehensive results. The paper simulated shapa coefficient of wind load as the model of a closed gable roof building, contrasting with the existing “structure load code”. It can provide the reference for the rational of numerical wind tunnel method,%基于数值风洞方法具有成本低、速度快、结果采集更为全面等显著优点,运用 FLUENT 软件,对封闭式双坡屋面房屋的风荷载体型系数进行了数值模拟,并与现行<建筑结构荷载规范>进行对比,为合理使用建筑数值风洞方法提供参考.
