Abstract The stability and strength of concrete columns confined by tangential and longitudinal external CFRP wrapping is studied. The plain and confined columns of slenderness l = 40 are tested. Two batches of concrete with different ultimate compressive strength are investigated. The theoretical prediction of ultimate strength and stability of columns coincides rather well with experimental results. It is concluded that additional external strengthening of confined concrete columns by attaching longitudinal CFRP sheets is efficient for concrete columns of moderate slenderness
