Abstract
Experiments on square and circular steel columns filled with light-weight concrete and high strength concrete have been conducted to investigate the contribution of these types of concrete to load bearing capacity of short composite columns. The aim of this research was to determine the effect of two types of concrete filling on behaviour of the composite columns. Thirteen specimens were divided in two groups: steel tubes filled with different type of concrete, with or without reinforcement and RC columns with same dimensions and shape, made of same type of concrete. Comparison was made between load bearing capacity of the steel tubes filled with light-weight concrete, and high strength concrete (with and without reinforcement). All specimens were tested by axial compression until to the failure state realization. Factors which influence the behavior and failure mode, ultimate strength, deflections and stress-strain relation were discussed.
