This paper presents results of testing 16 specimens, 12 of which as columns under different eccentricities
and four as beams under four point loading regime. All 16 specimens were circular in cross section and
were made of reinforced concrete. Four specimens served as reference specimens and were just made of
reinforced concrete. The next four specimens were wrapped with carbon fibre reinforced polymers
(CFRP). The next four specimens had steel fibres added to the concrete. The final four specimens were
reinforced with steel fibres and wrapped with CFRP. From each group of specimens, one specimen was
tested as a column under a concentric load, the second specimen was tested as a column under
25 mm eccentricity, the third specimen was tested as a column under 50 mm eccentricity, and the final
specimen was tested as a beam under four point loading regime. The experimental programme proved
that the introduction of fibres as well as wrapping the specimens with FRP improve the properties of concrete,
especially its ductility.
