Abstract: Due to the high parallel efficiency, convenient handling of complex grids and the ability to handle complex boundaries, the lattice Boltzmann method (LBM) has been used for building wind load simulation in recent years. LBM large eddy simulation was employed to conduct a numerical simulation of the flow field for a high-rise structure with a twin-spiral weather radar tower. The applicability and accuracy of the LBM method in simulating structural wind pressure were tested through combined wind tunnel experiments. The non-Gaussian wind pressure distribution characteristics on the surface of the double-tower structure under multiple wind direction angles were investigated. The results show that the LBM large eddy simulation method can effectively simulate the flow field distribution characteristics of the twin-spiral weather radar tower. The change trend of wind pressure at simulated measurement points under multiple wind direction angles is consistent with the results of the wind tunnel experiment. There are significant non-Gaussian characteristics in the fluctuating wind pressure in the twin-spiral tower area. The non-Gaussian peak factor calculated based on the transformation process method is significantly greater than the value obtained from the sample assurance calculation. The local peak factor in the dual-tower area generally exceeds the recommended value of 2.5, and the local maximum value exceeds 5.0, which is significantly higher than the peak factor in the square area. The research can provide relevant references for wind load calculations and wind-resistance design of the twin-tower envelope structures.
