Parametric 3d wind loading on hemispheric dome structures

Silva, Felipe Tavares da

Full Article:

Within the visual programming platforms in parametric design, it has not yet available with effective integration the CFD (Computational Fluid Dynamics) simulation systems. This coupling would be particularly useful in relation to the modeling of structures subjected to wind loads in a parametric and algorithmically programmed scenario. It is proposed in this work a parametric modeling of the distribution of wind loads on the surface of a hemispherical dome structure surface. From a combination of wind speed, internal and external pressure coefficient, dimensions of the building, topography and roughness of the terrain. It were defined the magnitude and direction of a field of distributed normal forces on the surface of the hemispherical dome and some results were obtained.
