A wind tunnel database for wind resistant design of tall buildings

摘要

Tall building models with various geometry shapes were tested in wind tunnel for their wind loads. The tested models can be categorized into two sets of wind tunnel studies. The first set is to study the wind load acting on buildings with different cross-sectional shapes. The second set of study emphasized on the effects of minor variations on building shape. The wind loads of building models were measured by high frequency force balance in the turbulent boundary layer flows. With sufficient wind tunnel data, then collaborating with proper structural dynamics procedure, a wind tunnel databased wind resistant design guide for tall buildings can then be built.
