| Abstract: |
A continuum model for a three-span suspension bridge with a floating girder is presented to investigate its dynamic behavior under moving loads and vertical support motions. This model can consider hangers’ extensibility. Coupled differential equations for the vertical displacements of a main cable and a girder subjected to external loads are presented. Equations of motion in matrix form are obtained by introducing the Galerkin method with shape functions for the main cable and the floating girder. A numerical example is used to verify the continuum model against a finite element model. |
