USE OF FIBER-REINFORCED POLYMERS IN SLAB-COLUMN CONNECTION UPGRADES

This article reports on an effective and reliable strengthening method for slab-column connection strengthening, which uses carbon fiber-reinforced polymers (CFRP) as shear reinforcement. Externally installed CFRP stirrups were used as the strengthening technique. The authors studied the effectiveness of different patterns, detailing, and various amounts of CFRP for strengthening. Results showed that the proposed method resulted in punching shear capacity increases up to 60%, relative to the specimen without any strengthening. The displacement ductility and postpunching resistance of the specimen also increased, resulting in a more ductile failure mode than that of the control specimen. The authors conclude that their proposed design guidelines are consistent with the design provisions of ACI 318-02.
