Abstract
The failure of most reinforced concrete structures is due to inadequate seismic design and detailing, poor construction techniques and/or the use of low-strength concrete (LSC). Retrofitting such structures with fibre-reinforced polymer wrapping rather than traditional concrete or steel jacketing is an emerging popular strengthening technique. In the research reported in this paper, carbon-fibre-reinforced polymer (CFRP) was used for external confinement of LSC bridge pier columns, which resulted in appreciable improvements in flexural strength and load-carrying capacity. Experimental tests and numerical simulations of quarter-size CFRP-wrapped circular columns under quasi-static cyclic loading were performed to evaluate the improvement in lateral load-carrying capacity. The results revealed that the confining action of the CFRP wrapping resulted in significant enhancements in the strength and ductility properties of the columns. It enhanced their energy dissipation capabilities and made them more able to tolerate even larger earthquake forces without an appreciable loss in stiffness.
