Abstract: This research study focuses on performance of SFRC filled GFRP tubes under axial compression and their composite behaviour. The main objective is to study the behaviour that various with parameters including grade of concrete, corner radius, thickness of the tube and cross section. The SFRC filled GFRP tubes were simulated choosing square and rectangular cross section areas of 133*133mm and 150*118mm having tube thickness 3 and 4mm with corner radius 10, 15 and 20mm. In order to obtain the good composite action the concrete with the compressive strength of 30N/mm2, 40N/mm2 and 50N/mm2 would be used. The height of the sections is chosen as 266 and 300 mm. The aspect ratio (H/D) was confined to two. The volumetric fraction of steel fibre used is 0.5%. The pultruded GFRP tubes would be used and the fibre orientation would be + 90°.3D model of the specimens is created and simulated using finite element software ANSYS. A new confinement model of 36 specimens are analysed in ANSYS and the results are tabulated. The ultimate loading capacity of the concrete filled rectangular GFRP tubes was arrived using the codal provisions available in ACI Code (ACI committee 440, 2R-08).
