Strengthening Bridges with Postinstalled Coiled Spring Pin Shear Connectors : State-of-the-Art Review

• Many existing bridge structures experience much more significant loads and load cycles than were anticipated when the bridges were originally designed. An effective way to increase the load capacity and fatigue resistance of steel girder with non-composite concrete deck bridge structures is to retrofit the structure with shear connectors to create a composite girder-deck structure. This paper presents a state-of the art study of post-installed shear connectors in general and coiled spring connectors in particular. The strengthening method is described together with experiences from real bridge strengthening projects, along with a study of load capacity and structural behavior.
