Title

Novel Frp-Concrete Composite Construction For The Infrastructure

Abstract

A novel composite column is proposed that is similar to the classic concrete-filled steel tubes, except that steel has been replaced with Fiber Reinforced Plastic (FRP) shapes. The FRP tube, while an integral part of the structure, is also the pour form for concrete. The tube may be a filament-wound pipe or a multi-layer FRP shape with a layer of longitudinal fibers sandwiched between two layers of circumferential fibers. The principle behind the proposed system is the same as in fiber-wrapping practice where concrete core is both protected and confined by a fiber jacket. A new passive confinement model is proposed for external confinement of concrete columns with fiber-wraps or FRP tubes. The model accounts for the varying lateral expansion of concrete (Poisson's effect), and the non-ductile behavior of fiber composites. Results are compared with recent studies of fiber-wrapped columns.
