摘　　要：采用CFD数值模拟方法探讨了常见的两栋相同的双坡屋面轻钢厂房前后布置时,在不同距离不同风向角下其屋面风压的变化及影响,并与单体工况比较,获得了群体效应下低矮双坡屋面房屋的屋面风压的分布规律和特性.本文的研究可供门式钢架厂房群体建筑的抗风设计作参考.The numerical simulation techniques are employed to study a common two dual -slope roof the same before and after the light steel plant layout, in different distances and different wind directions its roof and wind pressure changes in the interaction. Compared the result with single, the distribution trends of wind pressures on the surface of the building complex caused by the effect of multi - building interaction were analyzed. The results obtained in this design of groups of the light - weight steel buildings can be applicable to wind -resisting.
