Abstract
Summary: High torsional rigidity and attractive aesthetics in construction of twin-tub-girder bridges make them preferable for the design of curved bridges. However, according to the concepts associated with the term "Fracture Critical (FC)" that are in place today, all two-girder bridges are always classified as having FC members. For a steel bridge with FC members, the fracture of any of its members may result in complete catastrophic failure or significant loss of serviceability
