Experimental Investigation of the Load Carrying Capacity of Eccentrically Loaded Reinforced Concrete Elements Strengthened with CFRP

AbstractThe article analyses the behavior of eccentrically loaded confined rectangular cross section reinforced concrete elements. Fourteen elements were tested, 6 of which were strengthened with carbon fiber reinforced polymer. The influence of the eccentricity of vertical loading on the behavior of strengthened and non-strengthened elements was investigated. It was experimentally determined that the influence of concrete confinement decreases when loading eccentricity increases. It is necessary to take into account the decrease of the confined concrete strength when the load carrying capacity of eccentrically loaded element is evaluated
