Effect of Wind Loads on Low-Rise Pitched and Circular Arch Roof Structures: A Comparative Study based on Numerical Simulation

Through numerical simulations based on Computational Fluid Dynamics (CFD), this study examines the effect of wind load operating a pitched roof and circular arch an identical plan area storage structure with one wall opening. Many have been performed by other researchers for types roofs to understand behavior flow associated them. Also, standards multiple countries provided Coefficients Pressures standard building shapes. However, there is lack similar work structures having Ansys CFX fluid software has used carry out using k-ε turbulence model. The carried 7 incidence angles at interval 30ᵒ. Pressure, Force, Moment, Drag Lift generated were compared. It was found that, although variation in these coefficients w.r.t are both types, sharp-edged rooftop contributes higher magnitudes as compared smooth roof. Mathematical modules between face average pressure established polynomial form which could be find corresponding pressures forces arbitrary angles.
