Abstract In this research, a nonlinear finite element analysis using CEB-FIP 1990 code and Eurocode was performed to verify the confinement effect of a plate composite girder using CFT structures. In addition, a 50-m full scale specimen of the proposed composite girder was tested in a four-point bending experiment. The results of the experiment showed stable rigid behavior until the static actuator limit load (5,000 kN), which means that the stable rigid behavior is secured for the elastic limit load (3,200 kN) as well as for the service load (1,000 kN). The results of the nonlinear analysis and the experiment were similar until the static actuator limit load (5,000 kN). The comparison also indicated that the proposed analysis is a reasonable analysis method. The maximum displacement at mid-span of the composite girder was also compared to that of a common composite girder made only of steel. As a result, the ductility of the proposed composite girder was found to be higher than the common composite girder owing to the confinement effect.
