10th International Conference on Marine Technology, MARTEC 2016 Dynamic Analysis Of Floating Bridges

摘要

The main objective of this paper is to analyze the dynamic response of floating bridges with transverse pontoons, when subjected to harmonic regular wave loads. As a result, a simplified beam model of the Bergs0ysund floating bridge is established in the FEM software Abaqus. Additional "synthetic" floating bridge structures are subsequently built and analyzed in a similar manner. The pontoon model constructed in Genie is analyzed in HydroD to obtain the pontoon's structural model and hydrodynamic parameters.In addition to these parameters, by implementing the calculated data of mass and sectional properties of the bridge truss-work components, the simplified beam model of the bridge is built in Abaqus. Taking the Bergs0ysundfloating bridge model as the basis, "synthetic" bridge models are similarly assembled and studied. The effect of sideway mooring is also considered for the elongated bridge models.
