Abstract

Reinforced concrete structures have good fire resistance due to the inherited properties of concrete. Depending on the intensity and duration of fire, concrete properties deteriorate at different rates. Several researchers have documented the compressive properties of fire damaged concrete. Carbon fiber reinforced polymer (CFRP) composites have been successfully used for strengthening of circular column. Transverse wrapping of circular column could enhance confinement, shear resistance, enhance flexural ductility, and increase axial strength. CFRP wrapping increases the both axial strength and ductility of circular concrete columns, including the columns with low concrete compressive strength damaged by fire. This paper presents analytical investigation into the axial strength of fire damaged concrete columns strengthened with transverse CFRP wrapping. The results in this research suggest that CFRP wrapping should increase the axial strength of fire damaged circular concrete columns.
