In order to study the wind pressure distribution law of saddle-shaped membrane structure and investigate the surface wind pressure distribution characteristics of saddle-shaped membrane structure under three wind angles,such as 0°,45°,90°,etc,the ANSYS WORKBENCH platform was used to carry out numerical simulation and analysis of the wind load of saddle-shaped membrane structure at three angles,and the correctness of the numerical simulation method was verified by comparing with the standard model test of TTU.The results show that the finite element model matches the standard test.It is concluded that the non-Gaussian region of the wind pressure on the surface of the membrane structure changes under different wind angles,but all of them are concentrated at the edge position of the membrane.The non-Gaussian region delineation standard and the delineation schematic are given,and the reinforcement of the non-Gaussian region should be emphasized in the design of saddle-shaped membrane structure in order to improve the safety and stabili-ty of saddle-shaped membrane structure.
