Parametric Study of Longitudinal Seismic Pounding Response for RC Girder Bridge Based on Kelvin Impact Model

Abstract:

Article Preview

The pounding between adjacent segments of bridge has significant influences on its seismic performance, which is a complex nonlinear phenomenon involving many parameters. Based on Kelvin impact model, a simple-supported girder bridge was introduced to discuss the effects of impact stiffness and initial gap between joints. With dynamic analysis, it can be drawn the reasonable range for impact stiffness ratio and initial gap at expansion joint are respectively 0.05~0.2 and 0.04m~0.05m, which make the earthquake response of bridge reach a good balance.
