Larger attached canopies are very sensitive to the influence of wind and actually often damaged by wind force considerably. The purpose of the present paper is to describe the characteristics of fluctuating wind pressure and fluctuating wind force acting on a large-scale canopy attached to low-rise buildings with a flat roof. It also describes the characteristics of aerodynamics center that is estimated, based upon fluctuating stress generated in cantilevers supporting a canopy roof. The results of the present paper can be summarized as follows : (1) The properties of the wind forces acting on the attached canopy are considerably influenced by the properties of wind pressure acting on the upper side of canopy. (2) The peak of mean wind force coefficient and the peak of minimum wind force coefficient of upward direction acting on the center of attached canopy roofs can be evaluated by the empirical parameter with h/H and w/l. (3) The aerodynamics center of the peak minimum wind force acting on the center of attached canopy located at the center or slightly toward the tip side of the canopy length, and the aerodynamics center can be evaluated by the empirical equation.
