Abstract

This paper presents a series of test results carried out on elliptical Concrete-Filled Tube (CFT) columns. The tests were conducted to investigate the effects of variations of concrete strength and column slenderness on the behaviour and axial strength of the columns. The experimental study was carried out on ten specimens of short and long columns with Self-Consolidating Concrete (SCC). One elliptical steel section was used with three different typical concrete strengths to determine the reduction of column strength with the increase in column length. All specimens were tested to failure to assess their load carrying capacity, deformation and structural behaviour.
