Evaluation of the proposed wind force models by ASCE, for the purpose of building load design

In the present research a building with 45m height and 15m width is exposed to an uniform wind flow with a velocity of 31m/sec. Finite Element Method(FEM) is utilized to simulate the wind flow around the building. A two-dimensional model is presented and is used to calculate the turbulence viscosity. The flow field is solved with two different meshes and independency of results from the meshes has been achieved. The results for dynamic pressure computed by the FEM model are compared with those of ASCE; the results are in good agreement. Limitations of models presented in ASCE are discussed and the reasons of some differences between the FEM results and those of ASCE are presented.
