Abstract The stability and strength of concrete columns confined by tangential CFRP wrapping is studied. The plain and confined columns of different slenderness 16 < l <66.7 are tested. Two batches of concrete with different ultimate compressive strength are investigated. The theoretical prediction of ultimate strength/stability of columns coincides rather well with experimental results. It is concluded that external strengthening of concrete columns by CFRP tangential wrapping is efficient only for columns of moderate slenderness
