Research on Pounding Response at Expansion Joint in the Linear Bridge and the Curved Bridge under Earthquake
Aiming at pounding damage at expansion joint in a bridge under earthquake, the paper builds space dynamic models of a curved bridge and a linear bridge with expansion joint. Using nonlinear time history analysis, the paper contrasts the difference of pounding response at expansion joint in the linear bridge and the curved bridge and gives their simulation result under eight types of seismic input. The result indicates that the pounding response at expansion joint of curved bridge is larger and more obvious than that of linear bridge, especially at abutment expansion joint.
