Abstract: Over the past few years various studies are conducted to identify the behavior of concrete-filled steel tubular (CFST) columns. An investigation was conducted on a CFST column under axial loading. This paper mainly explores the carrying of the ultimate load in wood in filled CFST columns. The utilization of wood as inner core material to reduce the amount of concrete. For this research considering three pairs of specimens in each pair one specimen consist of wood. The dimensions of the three pairs are different and the two specimens in each pair have the same dimensions. Tests were conducted by loading frame. The confinement effect of steel tube and concrete filled in it guides the behavior of CFST columns. By the application of wood in CFST column properties like capacity, ductility, energy absorption will be enhanced. Experimental results are compared with Euro and Australian codes.
