Research on the Characteristics of Wind Load on L-Shape High-Rising Building

Abstract:

The mean and fluctuating wind pressures on an L-shape high-rising building were obtained through simultaneous pressure measurements in a wind tunnel. The shape coefficients on each surface and their variations with wind direction are investigated, which are more detailed than current load codes. Considering that there may be two composition forms, namely integrated-type and separated-type, when an L-shape high-rising building is structurally designed, the amplitude and frequency-domain characteristics of the base moment in along wind, across wind and torsion direction of the above two types are presented respectively. The research results show that the change regularities of shape coefficients on each surface with wind direction are different from each other and current practice using the shape coefficients of a certain wind direction to structurally design is worth discussing; the characteristics of three directions base moments on an integrated-type L-shape high-rising building are rather complicated and those on a separated-type building appear as obvious interfering effects.
