Experimental and numerical study on the effect of parameters in axial capacity of CFST columns with various L/D ratios
Abstract:Strength as well as behaviour of 16 circular concrete filled steel tube (CFST) sections submitted to axial compressive load was presented in this paper. Specimens having length to diameter (L/D) ratios of 3, 4, 5 and 6 with diameter to thickness (D/t) ratios of 38 as well as 25.33 with same outer diameter of 76 mm and two different wall thickness of 2 mm and 3 mm were considered to study the influence of column parameters and effect of confinement (Ꝣ). The ultimate capacities of CFST columns were compared with… Show more
