Abstract

This paper deals with experiment of the dynamic motion of an elastic floating bridge in winds and waves using a wave generator tank installed in a wind tunnel. The ends of the superstructure are moored by mooring devices with nonlinear restoring force characteristics in the horizontal direction transverse to the bridge axis. From the experiments, it is found that the dynamic motion of the floating bridge may be affected more strongly by the wave force than by the wind force. Moreover, the floating bridge is moved to the leeward side by the wind force and the dynamic motion by the wave force is done in the place after it moves. The analytical results with the computer program by the authors (Fumoto et al.,2006) for the dynamic elastic behavior of the floating bridge in waves are found to have good correlations with the experimental ones.
