In this paper, a new type of rectangular double-opening concrete filled sandwich steel tube (DCFSST) is developed. This new type of composite section can keep the inner steel tubes away from the cross-sectional centroid axis through the reasonable configuration. In order to assess the structural behaviour of rectangular DCFSST members, a pilot research on stub columns under axial compression was conducted. A total of 10 specimens, including 5 with double steel square hollow sections (SHSs) and 5 with double steel circular hollow sections (CHSs), were tested with the various offset rate of inner tube (
