Abstract

Abstract

To overcome the damage of bridge expansion joint, a static analysis model of semi-integral abutment jointless bridge was presented, the interactions among the superstructure, substructure and soil foundation of bridge were analyzed, a 100 m PC continuous box beam bridge with semi-integral abutment was studied by nonlinear geometric finite element method, the forces and deformations of the bridge undergoing dead load, vehicle load and temperature change load were obtained, the computation results of corresponding bridge with joint and integral abutment were compared.Analysis result indicates that the bending moment, shear force and deflection of the main girder and the axial force of the substructure for jointless bridge with semi-integral abutment are close to that of joint bridge, axial force appears in the main girder of jointless bridge, the bending moment and shear force of its substructure are bigger than that of joint bridge.As the damage of bridge joint is eliminated and the global stiffness of bridge structure is increased, semi-integral abutment jointless bridge is worth of application and popularization.
