Abstract :
The use of numerical prediction of wind loadsonto the structural model by computer simulation offer scertain advantages compared to the model tested in the wind tunnel.This study will look into the effectiveness and the suitability of FiniteElement Method (FEM) through numerical simulation usingFEMLAB software in the prediction of wind load effects to the structure. The wind flow and pressure distribution around the model are obtained from two-dimensional simulation of turbulence flow k-e. Two modelsof low rise buildings are chosen in order to compare the simulation results of the full scale and of the wind tunnel measurements. The predicted pressure coefficients Cp obtained from the simulation are thencomparedto previous studies using other methods suchas Finite Difference Method (FDM) and Finite Volume Method (FVM). Overall results of these two models show that the application of Finite Element Method (FEM) in two dimensional simulation are acceptable and comparable to the other methods for the wind ward face. Whilst, for leeward face the predicted pressure coefficient (Cp) obtained aremuch large rcompared to the real measurement.
