Abstract

The main objective of the study is to investigate the behaviour of light gauge steel hollow, Plain Cement Concrete (PCC) and Steel Fiber Reinforced Concrete(SFRC) in-filled stub, columns subjected to uniaxial loads Experimental and Theoretical investigations have been carried out. Specimens were fabricated from light gauge steel tubes. For PCC in-fill, M40 grade concrete was chosen and for SFRC in-fills, in the same grade of concrete crimped and hooked end steel fibers with aspect ratio of 60 were used for the volume 1.00% of both fibers. The effects of in-fill and eccentricities of the applied loads on the load carrying capacities of the hollow and composite columns were studied. Load-Axial shortening and Load-Strain behaviour for all the specimens tested. The failure modes, stiffness, ductility factors of the columns without in-fills and with (SFRC) in-fills were compared. Light gauge steel size (100 x 50 x 1500) and steel fiber size length 30mm dia 0.5mm.
