Title: Eccentric Loading of FRP Confined Reinforced Concrete Columns
Appears on pages(s):
Abstract: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 had steel fibres added to the concrete. The next four specimens were wrapped with Carbon Fibre Reinforced Polymers (CFRP). 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. For each group of specimens, axial force-bending moment interaction diagrams were drawn based on the experimental results and compared with theoretical estimation. 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.
