DYNAMIC-RESPONSE OF HINGED HINGED SINGLE SPAN BRIDGES WITH UNEVEN DECK

This paper investigates the effect of unevenness in the bridge deck on the dynamic response of single span bridge due to moving loads. For s implicity, the moving vehicle was modeled as a single degree of freedo m sprung mass moving with constant speed. The single span bridge was m odeled as either a simply-supported or hinged-hinged beam. The unevenn ess in the bridge deck is assumed to be a deterministic profile in the shape of a sinusoidal wave. The dynamic responses considering the eff ect of vehicle, unevenness, and bridge parameters are obtained and com pared between the simple-supported and hinged-hinged bridges.
