    Abstract

    Hybrid structures with concrete and fiber reinforced plastics (FRP) are regarded as efficient systems with pseudo-ductile characteristics and high stiffness and strength. This article presents the design, fabrication and testing of a new hybrid column made of concrete-filled FRP tube. The tube acts as formwork, protective jacket, confinement and shear and flexural reinforcement. Longitudinal and transverse stiffening ribs in the tube act as shear connectors and load distribution mechanism. Excellent shear performance was achieved in beam shear tests. Moreover, hybrid columns in compression control proved as strong in moment capacity as equivalent RC columns with over 5% rebars. (C) 1998 Elsevier Science Ltd. All rights reserved.
