Abstract: Concrete Filled Double Skin Tubular (CFDST) members have found wide spread acceptance in the construction industry due to their greater ductility, lighter weight and greater speed of construction. Glass Fibre Reinforced Polymer (GFRP) sheets are gaining much popularity as a confinement material along with retrofitting application. This paper presents a study on the behaviour of GFRP wrapped CFDST beam-columns subjected to reversed lateral loading. Comparison between the behaviour of the CFDST beam-column member with a Concrete Filled Steel Tubular (CFST) beam-column member is also presented. Tests were conducted on two CFDST specimens and two CFST specimens were subjected to reversed lateral loading under constant axial load. The CFDST column members were connected with CFST beam member by angle plates and bolts. M30 concrete with 40% cement replacement with fly ash was used to fill the space between the two concentric tubes. The lateral load-lateral displacement behaviour, ductility, energy dissipation, stiffness degradation and the peak load behaviour of the specimens are illustrated.
