The research investigated the behavior of reinforced concrete column stubs of telecommunication towers, which are strengthened with FRP fabrics. Six RC full-scale telecom column stubs with a square cross section and anchor bolts in the center were tested experimentally under concentric load. The experimental study is implemented to demonstrate the influence of confining FRP composite on the performance of telecom column stubs under axial loading. Parameters investigated by specimens were the influence of FRP number of layers, FRP type and FRP orientation on the axial load capacity, stiffness, ductility, and energy absorption of full-sized telecom stubs. The experimental results indicated significant enhancement in capacity and axial deformation of telecom column stubs fully wrapped with double unidirectional CFRP sheet when compared with double-wrapped heavy bidirectional GFRP light or heavy sheet. Examined specimens showed a noticeable increase in terms of strain values compared to unconfined specimens when the number of plies increased. Edges are circulated as FRP sheet ruptured due to the accumulation of confinement effect in specimens' corners. Ductility and energy absorption of column stubs wrapped with GFRP sheets were lesser than CFRP with the same plies number, even though GFRP was heavy-woven mesh sheets, not unidirectional light sheets. CFRP ductility index reached more than double the control by about 207%. It is noticed that load capacity calculations of telecom stub columns based on ECP 203–2020 and ECP 208–2015 calculations were more conservative than ACI 318–19 and ACI 440.2R-17 calculations when compared to experimental test results.
