The new reinforcement material, Hybrid Composite, is considered an innovative material, in that it can replace traditional steel reinforcement that employed to reinforce concrete. The new Hybrid Composite (HC) reinforcement is made of carbon and other fibers, which are arranged in a tubular weave or braid. Carbon fiber has been used in civil engineering applications, especially in column and pier. Carbon fiber sheets are wrapped around concrete columns to restrict the lateral expansion of concrete to improve the compression performance, while protecting the column as well. As a result of these attributes, HC tubes possess corrosion resistance, light weight, high strength, and good ductility. The material can be delivered to almost any length, easy to fold, unfold and pack, and thereby easy to transport. The dissertation addresses a feasibility analysis of HC reinforcement, but also analytic efficiency in the simulation procedure. As a new material to the civil engineering industry, we use a finite element analysis approach to identify key aspects of material utility and limitations. In this way, we reduce the experimental workload, and improve overall research efficiency. Based on experimental data is used to validate and check the finite element analysis. Due to the complexity of the model, new assumptions and approximations are tested. The approximations were found to improve computational efficiencies, which are generalizable to other related structural applications involving concrete reinforced with novel material
