Abstract

Aiming at pounding damage at expansion joint in a bridge under earthquake, the paper puts forward the new structure to cancel the expansion joint at abutment but reserve the expansion joint at pier between the two units in a bridge. Two different space finite element models of a bridge are built. Using nonlinear time history analysis method, the paper contrasts the difference of the dynamic characteristics and the seismic response between the bridges cancelled the abutment expansion joints and reversed the abutment expansion joints. The result indicates that the structure of cancelled the expansion joints at abutment can effectively improve the dynamic performance of the bridge structure.
