Numerical simulation of a conical roofed low-rise building to estimate the wind pressure coefficients

The roof shape and the slope of the roof are both significant constraints for the protection of the structure against wind load. The present study aims to investigate the variation of wind pressure coefficients on the conical roof and to observe the wind behavior around the building. CFD (Computational Fluid Dynamics) software ANSYS has been used for modeling and simulation. It is found that the 35° roof slope is the optimum roof angle for the present study, as there is the least area-weighted average pressure coefficient for this roof angle. While the roof slope 30° is found the most critical roof angle in terms of wind load resistance among all the roof angles of the present study.
