Abstract / Description of output
Ultra High-Strength Concrete (UHSC) have become increasingly popular within the civil engineering community. While many studies exist on structural members made using UHSC, research works on the behavior of Fiber Reinforced Polymer (FRP)-confined UHSC columns are scarce. Existing theoretical models for predicting the behavior of FRP-confined normal strength and high strength concrete found to be inadequate for FRP-confined UHSC with silica fume. Due to inconstancies of existing limited experimental results on FRP-confined UHSC columns, effect of silica fume cannot be clearly identified. This paper presents an experimental study on the compressive performance of twelve FRP-confined UHSC columns under axial compression. The variables investigated include unconfined concrete strength (two different mix designs with different silica fume content) and number of GFRP plies. While GFRP confinement significantly enhance both compressive strength and ultimate strain, effectiveness of GFRP confinement was found to be largely effected by the concrete mix design.
