    Post-fracture redundancy of the two-girder bridges is investigated through a case study of a three-span continuous twin I-girder bridge designed in Japan. The FE analysis is employed to evaluate the load-carrying capacity after the fracture of one main girder of the two-girder bridge. The critical locations include the mid-span section of the middle span, the side span, as well as the section near the continuous pier support. Besides, damage of studs near the moment contra-flexure regions in both middle and side spans are also considered in this study. Load-deflection response of the damaged bridge was compared with the intact bridge system, and the typical failure modes were described. Besides, the direct redundancy analysis results indicated that the present continuous twin-girder steel-concrete bridge can be classified as redundant. The concrete slab is considered as the significant member for redundancy of the two-girder steel-concrete composite bridges.
