低矮房屋风致干扰效应研究
Study on Wind-induced Mean Interference Effects between Low-rise Buildings
摘要
Abstract
Numerical simulation method based on computational fluid dynamics theory,which is verified by comparing wind pressure on low-rise gable roofed building of numerical simulation and wind tunnel test,is adopted in this paper to investigate interference effect between two such buildings considering various arrangement mode,arrangement distance and wind direction angle.Results show that there are most obvious wind-induced mean interference effects on cornice of interfered building for two same low-rise buildings.As for the arrangement of low-rise buildings,the tandem arrangement is largest,followed by staggered arrangement and less is parallel arrangement.Eventually,interference coefficients of wind load shape coefficient on the roof of lowrise gable roofed building in different arrangements are given to use for wind-resistant design of such buildings.关键词
