The static aerodynamic forces are composed of six components. Three components of them such as drag force, lift force and pitching moment are the biggest influence on the structure. These aerodynamic forces are generally evaluated from wind tunnel test or CFD. In this study, drag and lift force coefficients are estimated using relation of actual and analytical displacements. The actual displacements are measured by monitoring system when the bridges were under the typhoon. The analytical displacements due to uniform load are calculated by FEM. Also, the adequacy of estimation method was conformed by comparing the result of this study with that from the wind tunnel test of the similar bridge section.
