Minimum cost design of fibre-reinforced concrete-filled ...

Feb 01, 2005  This paper studies the minimum cost design of fibre-reinforced concrete-filled steel tube columns. It takes into account the effects of confinement of concrete and its steel fibre reinforcement. The constraints of the optimum design, prescribed by the strength and stability requirements, are adopted from the provisions of modern structural codes.

Concrete-Filled Steel Tubes - Composite Systems

Oct 10, 2012  Concrete-Filled Steel Tubes ( CFTs) are composite members consisting of an steel tube infilled with concrete. In current international practice, CFT columns are used in the primary lateral resistance systems of both braced and unbraced building structures. There exist applications in Japan and Europe where CFTs are also used as bridge piers.
