Renforcement des poteaux en béton armé au moyen de polymère renforcé par fibre de carbone : comparaison des codes

Abstract : The report includes calculation made to determine the parameters influencing the strengthening of circular, rectangular and square columns with carbon fiber-reinforced polymer "CFRP" externally bonded to the concrete by epoxy. According to these calculations, the main factors that reduce effectiveness of retrofitting by CFRP are the following: the number of plies, the geometry of the section, the radius variation of corners for rectangular and square section and the initial compressive strength of unconfined columns. Moreover, the comparison and evaluation of predictive equations between the compressive strength and ultimate strain of confined columns of three guides FIB Bulletin 14 2001, ACI 440.2R-02 and ACI 440.2R-08, led to discovery of an inaccuracy in the axial deformation formula, and a better results obtained from the equations used to calculate the compressive strength of confined concrete.
