In this study the frame based-FE model of road facility-supporting structures was created and analyzed to investigate the distributions of seismic forces according to the types of the supporting structures. From the results of response spectrum analysis, the first to third natural periods of most road facility supporting structures are ranged around an effective acceleration response zone in the design response spectrum and the base shear force and base moment increase as the size of the structures increases.
