This paper aims to provide a rational approach to the concept of circumferential strain efficiency factor ???of circular concrete columns wrapped with fiber-reinforced polymer (FRP) jackets. The variable ke reflects the reduction in the FRP hoop rupture strain observed in experiments, relative to the true rupture strain of the FRP material obtained from standard coupon tests or manufacturer datasheets. Currently, the ACI 440.2R-08 design guide uses a constant empirical ke factor of 0.55 for any column, regardless of geometric or mechanical properties.
