AIJ guide for numerical prediction of wind loads on buildings

This paper presents activities of the Architectural Institute of Japan (AIJ) on computational wind engineering, focusing on numerical prediction of wind loads on buildings. It discusses and evaluates current CFD techniques, including LES and modified RANS, for wind-resistant design of actual buildings. It also provides a guide for constructing a numerical model, including selection of a turbulence model, size of computational domain, required numerical discretization, etc.
