Faculty of Engineering - Papers (Archive)
This paper presents results of testing 16 specimens, 12 of which as columns under different eccentricitiesand four as beams under four point loading regime. All 16 specimens were circular in cross section andwere made of reinforced concrete. Four specimens served as reference specimens and were just made ofreinforced 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 werereinforced with steel fibres and wrapped with CFRP. From each group of specimens, one specimen wastested as a column under a concentric load, the second …

The majority of columns are subjected to a combination of an axial load and a bending moment in one or two directions. With a few exceptions, most of the research in the area of FRP wrapped columns have concentrated on the behaviour of concentrically loaded columns. This paper presents results of testing nine reinforced high strength concrete col-umns. The column specimens are circular in shape with 205 mm diameter and 925 mm height. Concrete compressive strength was 65 MPa. All columns were reinforced with steel. Three columns were not wrapped, three columns were wrapped with three layers of carbon FRP …

The use of steel reinforcement in concrete construction has proven to be very effective due to the excellent properties that the reinforcing steel has that compliment the concrete properties, for example increase in tensile strength and ductility. However, one of the drawbacks of steel is its long-term behaviour especially in areas where the humidity is high. In such areas, the steel usually suffers from rust and oxidation which eventually lead to the deterioration of the concrete structure. One method to reduce this effect is to protect the reinforcing bars, for example wrapping or using cathodic protection. This paper investigates the …

This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns, one column did not have any vertical straps, one had vertical straps made of one layer of wrapping material and one column had vertical straps made of three layers of wrapping material. All …
