This paper describes equivalent design pressure coefficients for beams supporting flat roofs. The distribution of mean pressure coefficients and gust factors of load effects for rigid and elastic beams supporting flat roofs are discussed based on the results of the wind tunnel tests, and the equivalent design pressure coefficients are evaluated. The equivalent wind pressure coefficient for rigid beams can be estimated with the scale effect factor and the aquaie of gust factor of windspeed at roof height. The equivalent design wind pressure coefficient for the elastic beams can be estimated with the equivalent wind pressure coefficient for rigid beams and the resonance factor. A more rational method for the evaluation of the wind load of flat roof beams than the conventional wind load evaluation method is proposed with the introduction of a new concept of the equivalent design wind pressure coefficient considering the load effect caused by the fluctuating wind pressures.
