The purpose of this study is to estimate axial and flexural capacities of circular concrete columns confined by carbon sheet tube. Fourteen uni-axial loading specimens and six full scale column specimens were tested by dynamic actuators. The main variables of this experimental works are number of carbon sheets and wrapping angles of carbon tube. Stress – strain relation of confined specimens was estimated by axial loading tests. Six full scale specimens were tested under constant axial load and cyclic lateral load. An equivalent stress block parameter was used to estimate flexural capacity of columns. Through the non-linear analysis, behavior of confined concrete columns under the cyclic lateral load were predicted.
