| Research Abstract |
CFD (Computational Fluid Dynamics) technique is recently expected as a sophisticated method for prediction of the wind loading, which definitely has a possibility to rationalize the wind resistant design for a building an a structure. An actual building has a complex shape and is surrounded by other buildings with different shape in the city. Aerodynamics of a bluff body such as a building and a structure tend to be easily affected by a delicate change of the configuration. So it is required to carefully estimate the aerodynamic forces on complex configuration and the presumption usually does not work well. In this case, we should measure individual aerodynamic forces on each configuration by an appropriate method. CFD probably has an advantage to predict the forces on various shapes of body, compared to the experimental method. In this study, we develop the prediction system based on CFD technique for wind loading on a building and a structure with complex configuration. Especially it is important for the prediction of wind loading to deal with turbulence effect. This study succeeds in simulating the wind flow around a building in the turbulent boundary layer and provides useful information of wind resistant design by numerical method.
