Computational Wind Engineering Development of Space Grid Design Software STADS--Wind Pressure Analysis. (English)

The wind pressure acting on the structure depends on the coefficient of wind pressure. Fluid-solid coupling analysis is a practical method to obtain the surface wind pressure of complex structure by the computational wind engineering (CWE) based on the knowledge of computational fluid dynamics (CFD), which has the advantages of low cost, short cycle and high efficiency. The interface program between STADS and ICEM, STADS and FLUENT is introduced, which automatically transfers the model to the pre-processing software ICEM. The wind pressure of the structure surface is obtained by using the fluid-solid coupling function of FLUENT through the interface program, and the shape coefficient of the structure surface can be automatically calculated and read. It can provide the calculation basis for the wind-resistant design of grid structure with complex shape. The complicated modeling process will be simplified by using this software, and the whole process adopts the operation mode of menu guidance and dialog box input, which is simple and easy.
