Numerical Study on Wind Pressures Caused by the Variation of the Rounding Radii of the Industrial Shed Eaves

Abstract

This work approached a typical industrial shed with varied rounded eaves, which is pointed out, in the few papers on it, as favorable to structural safety against the action of the winds. Since the literature has neglected this building configuration, the external pressure coefficients were obtained by CFD with the aid of the Ansys Workbench software, applying tetrahedral meshes in the domain discretization. Furthermore, the boundary layer around the building was modeled for greater accuracy in data capture. Using the RNG K-Epsilon model, were determined the turbulent flow effects. The results indicated a reduction in the pressure coefficients in the most sensitive regions and prone to accidents caused by wind on the roof. Finally, the flow pattern can be measured using the presented velocity fields.
