Effective parameters on the behavior of CFDST columns

Effective parameters on the behavior of CFDST columns

Concrete Filled Double Skin Steel Tubular (CFDST) columns could be considered as a new type of concrete filled steel tubular (CFT) columns. These columns are composed of two steel tubes in the concentric configurations with concrete between them. In the current study, finite element method was used...
