Influence of Wind Direction on Equivalent Static Wind Loads of a Super High-Rise Building

The joint distribution of wind velocity and direction is one of prime characters of wind load.The effects of wind direction on equivalent static wind loads of a super high-rise building were studied.The main contents are as fellows:(1) The meteorological data at the location of the building are firstly acquired and the design wind velocity corresponding to each wind direction was calculated.(2) The pressure measurement test of the building was conducted by using the synchronous multi-pressure scanning system in wind tunnel and surrounding building was simulated in wind tunnel test.(3) The equivalent static wind loads corresponding to each wind direction were calculated based on wind tunnel results and stochastic vibration theory.The conclusions of this paper are useful for the wind-resistant design of high-rise buildings.
