The synergistic interaction of steel and concrete in concrete filled tube (CFT) composite members improves structural performance by delaying local buckling of steel tube. Compared to localized confinement provided by discreet ties in reinforced columns, the steel tube provides continuous confinement to infill concrete which results in improved energy dissipation and ductility performance. Concrete filled tubes (CFTs) provide improved structural strength and ductility while minimizing the cost of column formwork. The construction sequence of CFT allows its use for accelerated bridge construction applications. The use of CFTs for bridges in the U.S. has been limited mainly due to lack of …
