Seismic Behaviour of FRP-Retrofitted Concrete Columns
Retrofitting of concrete structures with fiber reinforced polymers is a relatively new technique. In an extensive research program underway at the University of Toronto, effectiveness of FRP in enhancing structural performance both in terms of strength and ductility is being investigated. The structural components tested include columns, beams, slabs and bridge culverts. Research on columns has focussed on improving their seismic resistance by confining with FRP. Results from a select group of eight circular and four square columns are presented here. All the columns were subjected to simulated seismic loads. Based on a comparison of the moment-curvature responses of the critical sections of FRP-retrofitted specimens with those of similar companion specimens with FRP, it can be concluded that FRP wraps significantly improved the seismic resistance of columns.
