摘要:
鉴于高层开洞良好卸载效果与迎风面突然开洞的破坏作用,提出对低层轻钢结构开洞抵御风荷载的气动措施.通过湍流κ-ε方程和结构化非均匀网格,采用风洞实验验证的数值风洞模型模拟了4个开洞位置不同,但尺寸相同的轻钢建筑,并基于以上模型风荷载分布提出主动抗风的结构形式.分析结果表明,开洞房屋屋面平均风压较低,此种结构在强风作用下比同类型全封闭的结构抗风性能要好.
Abstract:
Considering good unloading effect of openings on high buildings and damage from unexpected openings on windward surface,the aerodynamic measures are put forward to resist wind load through openings.Through κ-ε turbulent equation and unequal net of structure,four light-weight steel construction models with same dimension but with different locations of openings are simulated by numerical models validated by wind-tunnel.Based on the distribution of wind load in these models,active wind-resisting structure system is presented.It is suggested that active wind-resisting structure system owns better wind-resisting capability than completely enveloped structure,due to the lower average wind pressure on roof.
