Developing Composite Action in Existing Non-Composite Steel Girder Bridges

This paper describes the results of a study investigating methods to strengthen existing non-composite steel bridge girders using post-installed shear connectors. Four non-composite steel-concrete beams representing existing non-composite bridge girders were strengthened using three types of post-installed shear connectors. The full-scale, retrofitted partially composite beams were tested under static loading to evaluate their strength, stiffness, and ductility. One non-composite beam was also tested as a baseline specimen. Results of the study indicate that the addition of a relatively small number of post-installed shear connectors can increase the load-carrying capacity of non-composite girders by more than 50 percent. Based on the results of this study, a design approach based on partial composite action was developed for strengthening existing steel bridge girders by using post-installed shear connectors.
