Concrete-Filled Steel Tubes - Composite Systems
Concrete-Filled Steel Tubes - Composite Systems

10/10/2012, · 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.
