Abstract

This paper describes the new wind load recommendation proposed by Architectural Institute of Japan in1981.The wind load is led from the consideration of buffetting phenomana of buildings in turbulent strong winds caused by tropical and temperate depressions.Two kinds of wind load are proposed;one is for structural frame designs and the other for cladding designs.Component parts of the wind load are basic annual maximum wind speed, return period of design wind speed, surface roughness, vertical wind speed profile, shape factor and gust loading factor.Cust loading factor is deduced by statistical methods proposed by Davenport and others.The recommendation also includes some comments on vortex exciting oscillations and other types of aerodynamical oscillations.
