Vibration of railway arch-bridges shaken by vertical support motions
Original language description
The aim of this paper is to investigate the vibration of an arch bridge under the simultaneous action of moving train-loadings and vertical support excitations. The arch bridge is modeled as a flat-rise parabolic arch with constant sectional properties along the horizontal axis of span, and the train loadings over it as a sequence of identical lumped loads with constant intervals. Since this study deals with the dynamic response of a bridge with non-homogeneous time-dependent boundary conditions, quasi-static decomposition method is employed to separate the total deflection response of the arch bridge into quasi-static deflection and the dynamic component of deformation. Then one can obtain the closed form solution of quasi-static deflection for the arch bridge shaken by vertical support excitations in an analytical manner.
