Calculation of Reinforced Concrete Columns Strengthened by CFRP
Abstract In this paper the results of calculation of eccentrically compressed reinforced real scale concrete columns strengthened with carbon fiber reinforced polymers (CFRP) laminates is presented. In order to check the calculation results, four real scale experimental reinforced concrete columns 2200 mm long and with sectional dimensions 180 × 140 mm were manufactured. Reinforced samples were strengthened with a 25 mm CFRP laminates. The calculation was made according to Eurocode 2. The usage of carbon laminates limit strain introduced into the calculation, is proposed. On the basis of normative documents the block diagram of calculation algorithm for such structures is created. As a result of the calculation it was established that according to the presented calculation algorithm the divergence between calculated and experimental values reaches 5 … 10%, while the experimental data exceeds the theoretical ones. It makes it possible to reliably calculate and design strengthening of eccentrically compressed RC structures with CFRP laminates according to the algorithm presented in the work.
