Fabrication And Testing Of Curved Tubular Flange Girders

The project will design, fabricate, and test a new steel girder system for curved highway bridges. The system, known as the curved tubular flange girder (CTFG) system, has been studied extensively using numerical simulations, but has never been fabricated or tested in the laboratory. The CTFG system has been shown to have considerable technical advantages over the conventional curved steel I-girder system. The project will enable Lehigh and High Steel Structures to work together in developing the CTGF system for highway bridges.
