Abstract
The acceptance that fibre reinforced polymers (FRPs) have so far gained for new structures is not in proportion to their potential, because their short-term costs are usually higher than those for structures with conventional materials. Designers and owners have usually justified the use of FRPs in new structures on the basis of life-cycle costing. The same is not the case for rehabilitation of existing structures with FRPs. The FRPs are highly cost-effective for rehabilitation, mainly because of their light weight and ease of bonding them to existing structures. A few of the several innovative applications of FRPs in this respect are described briefly in the following Sections, it being noted that the design provisions of all these rehabilitation techniques are covered by the Canadian Highway Bridge Design Code (CHBDC 2006). It is recalled that the CHBDC defines rehabilitation as ‘modification, alteration, or improvement of the condition of a structure that is designed to correct deficiencies in order to achieve a particular design life and live load level.
