Abstract
The effectiveness of near-surface mounted glass fibre reinforced polymer (NSM-GFRP) reinforcement to upgrade shear capacity of concrete T-Beams with corroded stirrups is examined in this paper. A total of seven beams were tested. Test variables included level of corrosion in stirrups, 8% and 15% cross section loss, and spacing between the NSM-GFRP rebars, 120 mm and 60 mm. The reduction in shear capacity attributable to corrosion was proportional to the reduction in the stirrups cross section area. At the lower stirrups corrosion of 8%, the NSM-GFRP strengthening compensated the reduction in shear capacity and provided an additional increase over the capacity of a control undamaged beam. The effectiveness of the NSM-GFRP strengthening reduced with increased level of stirrups corrosion. At the higher stirrups corrosion of 15%, only the NSM-GFRP strengthening with the lower spacing restored the shear capacity of the corroded beams. Results of the experimental tests were compared with predictions of published analytical procedure.
