NUMERICAL PREDICTION OF WIND LOADING ON BUILDINGS AND STRUCTURES - ACTIVITIES OF AIJ COOPERATIVE PROJECT ON CFD

This study presents the activities of the Architectural Institute of J apan (AIJ) concerning the Computational Fluid Dynamics (CFD) for a num erical prediction of wind loading on buildings and structures. In the AIJ project, the flows and the pressures around a low-rise building (b readth : depth : height = 1 : 1 : 0.5) have been computed by 10 member s of the working group, who mainly employed the k-epsilon model or the large eddy simulation for turbulent flows. Here, on the basis of the results of the AIJ project, future subjects for further development of the CFD technique are discussed. Also we present how to find the way to realize the practical use of the CFD technique on prediction of win d loading.
