Bond-slip behaviour of concrete-filled stainless CHS tubes was investigated. Contact face of the inner concrete slightly was crushed. 70% of bonding strength is taken by the interface friction force. 30% of bonding strength is sustained by the chemical adhesive force and the mechanical interlock force.
