Abstrakt:

Short and medium span continuous steel-concrete composite (SCC) girder bridges are becoming more and more popular. The problems caused by the negative bending moment in the continuous SCC girders cannot be ignored. In order to investigate the performances of the continuous joints between adjacent SCC girders, consist of steel endplates and headed shear stud connected to concrete cross-beam, the finite element model was built by using ABAQUS software, of which the accuracy was verified by experimental results. The parametric analyses were carried out to investigate the influences of the strength and reinforcement ratio of the concrete slabs in SCC girders, and the diameters of the horizontal headed shear studs on the performances of the joints. The ultimate moment capacity of the joint increases with the increase in the strength and reinforcement ratio of concrete slab and the diameters of the horizontal headed shear studs.
