Abstract

The paper reports results from the second phase of an experimental research programme on the behaviour of concrete beams strengthened with reinforced polymers. The work presented here refers to results from bond tests of polymer strips glued on rectangular concrete prisms. Concrete mix for the prisms was designed with a view to simulating the concrete strength that was used in Greece during the period from 1960 to 1980 for residential and office buildings. Various configurations of SRP (Steel Reinforced Polymers) and CFRP (Carbon Fibre Reinforced Polymers) strips were bonded to ten rectangular concrete prisms using epoxy resin. The main parameters of the tests were the fibre type (steel, carbon), strip length, and strip width. For each specimen the deformation law (bond strength vs. total slip) up to maximum strength and elongation at failure, was recorded. Tested materials were classified according to their debonding strength and deformation capacity. Useful conclusions were drawn with respect to the influence of reinforced polymers length and width on the strength and deformation capacity. Analytical models available in the literature were applied, and the one proposed by Chen and Teng was found to better match the experimental measurements, and is thus recommended for the estimation of bond strength for materials such as those tested in the present study. Results from the tests reported herein were taken into account for the design of the flexural and shear strengthening scheme of thirteen concrete beams for the last (third) phase of the experimental programme.
