| Abstract: | Aimed at pounding damage of expansion joint in a curved ramp bridge under earthquake,relying on a multilevel junction system project,the pounding between expansion joints at pier table and abutment table under earthquake was simulated by using Kelvin contact element.The space dynamic model of a single curved ramp bridge including piers,beams,bearings and expansion joints was built.By using nonlinear time history analysis method,different pounding responses between expansion joints at pier table and abutment... |
