摘　　要：为明确台风引发住宅入户门安全事故的机理,以台风风向、入户门开角为自变量,采用CFD数值模拟方法,搭建某住宅的台风绕流模型,通过虚拟实验得到台风绕流压强场,再对比分析不同工况下入户门表面的风压分布及风载荷大小,进而确定引发入户门安全事故的主要因素。结果表明:台风下入户门所受风载荷大小与风向密切相关,与门开角的关联性不大;当台风风向为20°时入户门所受风载荷最大,最易引发入户门安全事故。In view of a clarification of the mechanism of safety accidents brought about by typhoons on residential entrance doors,a CFD numerical simulation method has been adopted with typhoon wind direction and entrance door opening angle as independent variables to build a typhoon flow model for a certain residential building,thus obtaining the pressure field of typhoon flow based on virtual experiments,followed by a comparison and analysis of the wind pressure distribution and load size on the entrance door surface under different working conditions so as to determine the main factors causing entrance door safety accidents.The results indicate that the wind load on the entrance door under typhoons is closely related to the wind direction,but not much related to the door opening angle;with a 20°wind direction of a typhoon,the maximum wind load thus obtained on the entrance door is likely to cause safety accidents.
