The project concerned fatigue testing and numerical evaluation of a steelcomposite hybrid girder. The girder was previously built under collaboration between Maglev Inc. and Lehigh University. The girder was instrumented with strain gages and LVDTs to monitor strains and deflections. A test setup with bottom supports and towers for mounting two or three hydraulic actuators was installed in the ATLSS test lab. The girder was fatigue tested for over 300,000 cycles at loads up to 120 of design load. There was extensive cracking in the steel structure, but only minor damage in the composite panels towards the very end of the test.
