Cyclic Lateral Response Of Frp-Confined Circular Concrete-Filled Steel Tubular Columns, Tao Yu, Y M. Hu, Jin Guang Teng

Faculty of Engineering and Information Sciences - Papers: Part A

Concrete-filled steel tubular (CFT) columns are widely used as columns in many structural systems and a common failure mode of such tubular columns is inelastic outward local buckling near a column end. The use of fibre-reinforced polymer (FRP) jackets/wraps for the suppression of such local buckling has recently been proposed and has been proven to possess excellent potential in both retrofit/strengthening and new construction. This paper presents the results of an experimental study into the behaviour of large-scale FRP-confined CFT (CCFT) columns under combined axial compression and lateral loading. The test parameters included the stiffness of the FRP jacket and …
