| Summary: | The use of numerical prediction of wind loads onto the structural model by computer simulation offers certain
advantages compared to the model tested in the wind tunnel. This study will look into the effectiveness and
the suitability of Finite Element Method (FEM) through numerical simulation using FEMLAB 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 models of 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 then compared to previous studies using
other methods such as 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 windward face. Whilst, for leeward face the
predicted pressure coefficient (Cp) obtained are much larger compared to the real measurement |
