Abstract:

This paper presents the results of a study examining ways to strengthen existing non-composite steel bridge girders using post-installed shear connectors. Five full-scale beams were tested to evaluate structural performance of composite beams retrofitted with post-installed shear connectors. Results of the study indicate that the addition of a relatively small number of post-installed shear connectors can increase the load capacity of non-composite girders by a factor greater than 1.5. 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.
