This paper presents research on the reinforced concrete-filled steel tubular (CFST) members subjected to eccentric tension, where the embedded components are the reinforcing bars or steel angles. A total of 8 full-scale specimens were designed and tested with main parameters of specimen types and load eccentricities. In particular, there was no direct connection between the outer tube and embedded components. Therefore the tensile load was transferred from the outer steel tube to the reinforcing bars or angles through the filled concrete. The failure mode, the load versus deformation relationships and the strain responses were recorded and analysed. The simplified design equations were also proposed for the elastic tensile stiffness and tension versus moment interaction relationships of reinforced CFSTs under eccentric tension.
