Abstract : In the present paper the experimental and numerical study carried out on the two models of high-rise buildings under different value of wind velocity with 0 degree of wind attack. Two shapes of building namely square and triangle are considered. Pressure measurements are made on the rigid models of high-rise buildings made of timber. The models are tested in a wind tunnel. (3D) ANSYS (Fluid Fluent) was employed with finite volume method to predict the wind pressures on high-rise building using specified boundary conditions. RNG k-ε turbulence model was applied for square shape and Spalart-Allmaras turbulent model for triangle shape in order to simulate the wind turbulence. It is concluded that wind pressure resulting from wind tunnel test have a very good agreement with the wind pressure results from CFD for different value of velocity for two models. It can be seen from a comparison that the design pressure of the square model is less than the design pressure of the triangle model with different speed and the percentage of difference is about (20-25%).
