Carbon fiber, owing to its greater strength-to-weight ratio, has found its application in civil engineering and architecture as well. Carbon fiber reinforcement can be used for concrete columns instead of the traditional steel bar reinforcement. Carbon fiber provides not only additional strength but also encases the concrete, acting as a protective cover. It increases the reliability of the reinforced concrete columns at a lower service cost. This is especially useful in coastal areas or hilly areas, where the structure is prone to environmental damage or is difficult to be constructed by conventional methods. The effectiveness of these columns is a function of a number of factors which include the nature of fiber reinforcement, width of fiber wall, slenderness ratio and type of concrete used, among others. In the present research, the compressive strength of circular composite columns is determined as a function of three parameters, namely the diameter of column, thickness of carbon fiber wall and strength of concrete. To develop relations between these three parameters, fifteen fiber-reinforced columns are fabricated using the standard procedures, filled with concrete of various grades, and tested for compressive strength. The results of the compressive test further act as input to a design of experiments software, Design Expert 12.0, which provides regression equations for compressive strength as a function of the aforementioned input parameters.
