大跨度悬挑屋盖的风驱雨压干扰特性研究
Research on Wind-Driven Rain Pressure Interference Characteristics of Long-Span Cantilever Roofs
摘要
Abstract
By using numerical simulation,the interference factors of measuring points and zoning were de-fined,and the pressure of the target building before and after the interference of the interfering building was analyzed.Specifically,the height difference,spacing,wind direction angle,wind speed,and rainfall in-tensity between the target building and the interfering building are used as interference factors to explore the variation law of the interference factors on the roof surface of the large-span cantilevered roof model.The conclusion is drawn thatas the height difference increases,the reduction effect of the target building will also increase.As the spacing increases,the reduction effect will decrease.When the wind direction an-gle is 90°,the roof is subjected to the maximum amplification interference effect,the maximum reduction effect is observed under the 0° wind direction angle condition,and the minimum reduction effect is observed under the 45° wind direction angle condition.When the wind speed is 16.7 m/s,the roof surface experiences the maximum reduction effect,while when the wind speed is 10 m/s,the roof surface experiences the mini-mum reduction effect.The interference effect will increase with the increase of rainfall intensity.关键词
