Abstract

The results of an experimental investigation on the behavior and performance of reinforced concrete beams strengthened in flexure is presented. The strengthening procedures consisted on the increase of the concrete and rebar section and was subjected to loads a few days after its completion. Special attention is given to the loading conditions at time of the repair. Four series of beams were tested. Series 2 and 3 were repaired and differed only in the terms of the applied load during the strengthening procedures. Series 1 and 4 were cast at one time and had the geometry corresponded to the beams before and after the intervention respectively. The performance of the repaired beams (Series 1 and 2) showed good agreement with the beams of Series 4. The experimental results are also compared to theoretical values and those obtained employing the Brazilian Code criteria. Good correlation is also achieved.
