Abstract
This paper investigates the comparison of external passive and active confinement to restore the strength, ductility, and durability of affected RC columns to an acceptance level using carbon fiber reinforced polymer (CFRP) bands. The experimental program included compression load testing of square and circular-shaped reinforced concrete columns to establish the effect of the confinement on the compressive load-carrying capacity and the stress–strain behavior. A number of parameters are investigated in the study including the effect of varying the band spacing, confining pattern, and passive and active confining forces. It has been found analytically that confining the columns with prestressed CFRP bands did optimize the load-carrying capacity economically. It also enhanced the confined column’s stress–strain behavior with greater lateral stresses at peak strength observed as well as the ductile property.
