摘要：

The dynamic response of floating bridges consisting from simply connected non-deformable pontoons under the action of a moving load with constant velocity is thoroughly studied. Taking into account the moving load, the buoyancy forces and the forces due to waves, the dynamic equilibrium is expressed by a set of dynamical equations of motion with respect to the joints between pontoons. The gathered nonlinear equations of motion are solved using the numerical method Runge-Kutta and the dynamical deflections of the joints between pontoons are shown in related diagrams for several velocities of the moving load and characteristics of the waves.
