Abstract

Ultra High Performance Strain Hardening Cementitious Composites (UHP-SHCC) is a new strain hardening composite with outstanding mechanical and protective performance. In this study, UHP-SHCC was applied to RC beams as a tensile strengthening material, and the beams were tested under four-point bending setup. It was clarified that strengthening by UHP-SHCCs significantly contributed to increasing the load carrying capacity. And stress-strain relation obtained from the tensile tests can well simulate the response of the strengthened beams.
