Review on Composite Hollow Steel Columns Filled With Light Weight Concrete

Abstract

Concrete filled steel tube column is becoming popular in construction industry; there are several research works on its behavior. Recently, there are studies on light-weight concrete filled steel tube (LWCFST) column under axial loadings. Advantages of light-weight concrete over normal concrete brought about the research on the use of light-weight concrete in concrete filled steel tube column. This paper review studies done on light-weight concrete filled steel tube columns. Axial load capacity, failure modes and codes comparison done by different researchers were presented. There is a need to study detail behavior of light-weight concrete filled steel tube column especially using numerical analysis.
