    • Abstract
  • In order to estimate the vertical displacements of a floating bridge subjected to moving heavy loads, the floating bridge is simplified as an elastic-base-beam, and then the dynamic response is solved accordingly. The static vertical displacements and the dynamic responses induced by a single moving load or two moving loads are calculated and compared with those obtained by dynamic displacement tests under the same conditions. It is shown that the calculated results by the proposed method can satisfy the precision requirement in engineering. Moreover, the method can be performed conveniently for the estimation of dynamic responses and vertical displacements of the floating bridge in different cases.
