In our country,the wind load is researched through the wind tunnel test or CFD software toanalyze the wind pressure distribution on the buildings.In this paper,the computer numerical simulation,wind tunnel test and project analysis are joint used to get further guidance on the wind-resistantdesign of the building structure.The FEM software ANSYS 11.0 is applied to build the finite elementmodel of the house.The wind pressure value which is got through the test points in the wind tunneltest is loaded on the FEM model.The stress response in different wind direction is calculated throughANSYS.The strength of the main load-bearing structure roof truss is especially analyzed andchecked.The result shows that this method has more significance on the guidance of the structure design.
