山地风场中圆形截面超高层建筑风荷载谱
Analysis of wind load spectrum of super tall buildings with round section in hilly terrain wind field
摘要
Abstract
In order to get wind load and wind induced response of super tall buildings in hilly terrain wind field,effect of changing of turbulent intensity on wind loads must be known.4 kinds of turbulent wind field are simulated,and 3 super tall building models with round section of different aspect ratio are manufactured.Effects of turbulent intensity,aspect ratio and layer height on along-wind and across-wind load are discussed.Different models are used in fitting of wind load spectrum on each direction.Parameters of load spectrum models are secondary fitted based on turbulent intensity and aspect ratio.Mathematical models of wind load spectrum of super tall buildings with round section in hilly terrain are preliminarily established.At last,an example is provided.According to vertical profile of mean velocity,turbulent intensity and mathematical model of wind load spectrum,wind induced dynamic response of super tall buildings in hilly terrain and flat terrain are compared.关键词
