Abstract

This study examines the in-situ shear performance and modes of failure of reinforced concrete (RC) T-beams (joists) strengthened with externally bonded carbon fiber reinforced polymer (CFRP) sheets. The experimental program consisted of testing a series of nine structural components at the Malcom Bliss Hospital, in St.Louis, Missouri. The members were tested to validate the different systems and techniques of strengthening. In particular, this paper covers cases of U-Wraps with and without end-anchors. The experimental results clearly indicate the contribution of externally bonded CFRP sheets in increasing the shear capacity of the system. The experimental and theoretical shear strength of the reinforced concrete members (RC) under investigation is presented with and without anchorage.
