DEVELOPMENT AND TESTING OF A NEW SHEAR CONNECTOR FOR STEEL CONCRETE COMPOSITE BRIDGES

A new cross section has been developed for steel concrete composite bridges that eliminates the top steel girder flange. This is made possible by utilizing a recently developed shear connector known as the Perfobond Strip. This shear connector provides a stiff connection between steel and concrete and reportedly has excellent resistance to fatigue. Because the success of this new cross section and numerous other applications depends on the performance characteristics of the shear connector, the present design models were investigated. Some inconsistencies were found between current design models and experimental results; the results of a series of shearbox tests that have led to the development of a new design model are included. This new design model is compared with current models. Some details of a full-scale bridge test are also included to examine the fatigue behavior and overall performance of the new bridge cross section.
