Abstract

The confined reinforced concrete columns with carbon fiber reinforced polymers are used in a wide range in repair, strengthen and rehabilitation. Many of experimental and theoretical studies have been done for understanding their behavior, but these studies hinge on making the confinement process before loading or preloading. In this paper, the full and partial confined stored loaded RC columns with carbon fiber reinforced polymer (CFRP) were confined under different applied load values equal to 0.0%, 20.0%, 40.0%, and 60.0% of the maximum load of unconfined RC columns presented the service loads. The special test set-up for stored applied loaded was used to simulate the cases in the practical field. After that, the columns were retrofitted with CFRP with leaving 48hours up to the recommended strength. Then the loading is continuous up to failure. Thirteen tested RC columns were divided into four groups in the experimental program. The type of confinement (full or partial) and type of section (square or circular) were the studied parameters. The results shown that the load carrying capacity of confined stored loaded RC columns with CFRP decreased by increasing the stored applied load at confinement process. Moreover, the stored applied loads at the confinement process caused increasing in the axial strain and decreasing in the radial strain at the maximum load. The new proposed equation calculates the ultimate load of the confined RC column with CFRP considered the effect of stored applied loads was presented. For understanding the real behavior of confined stored loaded reinforced concrete columns with different parameters, more studied must done.
