Abstract:
In the rehabilitation of composite concrete and steel structures, oftentimes inadequate shear connection between the two materials is found. As noted in the statement of research significance, established methods of adding shear connectors by welding are unacceptable since the type of steel in many old structures is undknown. This article presents two methods of using high-strength bolts as shear connectors. Two series of push-out tests involving two different bolt configurations were done; for comparison, a third series of push-out tests with welded steel connectors was also accomplished.
