| Research Abstract |
This study, focusing on the CFD technology as a comprehensive tool based on the creative and original concept, have aimed at providing the new method for wind resistant design for buildings and structures. The research items are firstly to apply the CFD method to the design of actual buildings and to elucidate the relation between the predictive accuracy of the wind loading and the requirement correct level for the wind resistant design. Also, assuming the meteorological event with regard to the typhoon, we give the high wind velocity data for wind resistant design by estimating the high wind local area in city. Finally considering the circumference environment of the construction site, this study provides important techniques concerning various boundary conditions or treatments for performing the wind resistant design based on the CFD as a result of the detailed LES (Large eddy simulation) analysis of high wind impact on buildings.
