Abstract
The geometry of a building is one of the influential parameters in calculating the wind load. This parameter is denoted as Cp in static methods. It is provided in codes for conventional buildings. The present study calculates the wind pressure coefficient for a non-conventional Y-shaped building model with a scale of 1:500. To obtain the wind effects on the building, the wind tunnel test and computational fluid dynamics (CFD) were employed. The model was rotated in 10-degree rotation steps within the wind tunnel to find the most critical wind load orientation. Also, the wind pressure was applied to the building in the CFD approach to obtain the maximum displacement. The largest displacement (relative to the original position at θ = 0°) was found to be 3.75 at θ = 30°. The numerical results were found to be in good agreement with the experimental wind tunnel results. This demonstrated that the proposed method could be a suitable alternative to the wind tunnel test.
