Tests of Horizontally Curved Tubular Flange Girder System

Tubular flange girders (TFG) are an innovative I-shaped steel bridge girder proposed for horizontally curved bridge systems. The I-shaped TFG has a steel tube flanges rather than a conventional flat plate flange for one or both flanges. The closed tube section significantly increases the torsional stiffness of the section and the open I-shaped section provides flexural stiffness.

Probabilistic Seismic Performance Assessment of Low-Ductility Concentrically Braced Frames in East Coast U.S.

The overall objective of this dissertation is to advance knowledge on the seismic behavior and performance of low-ductility concentrically braced frames (CBF) in the mid-Atlantic east coast region of the United States (ECUS). Low-ductility CBFs in the ECUS are usually designed with a Response Modification Factor R equal to 3 and without seismic detailing to promote ductile behavior.
