Abstract

In recent years, fiber-reinforced polymer (FRP) composites have found wide applications in new construction. A popular type of hybrid member incorporating FRP is the concrete-filled FRP tube (CFFT), consisting of an FRP tube filled with plain or steel-reinforced concrete. CFFTs have several advantages over traditional column forms, including their excellent corrosion resistance and ductility. Much research has been conducted on CFFTs over recent years, but no systematic procedure for designing such members has been developed, which has been one of the factors preventing CFFTs from becoming more widely accepted in practice. This paper presents a summary of the design provisions for CFFTs given in the Chinese Technical Code for Infrastructure Application of FRP Composites and explains the rationale behind these provisions. These provisions have been developed on the basis of available research and work undertaken at The Hong Kong Polytechnic University.
