The invention relates to a concrete-filled steel tubular column, comprising a steel tube and truss structures. The truss structures are arranged on the inner wall of the steel tube, two or more web member ribs of each truss structure are bent in a 'W' shape, wherein first bent parts of the two or more web member ribs are connected correspondingly, second bent parts of the web member ribs are arranged on the inner wall of the steel tube at intervals, bending or inclination of a single web member rib relative to the tube wall of the steel tube is avoided, and the arrangement stability of the truss structure on the inner wall of the steel tube is improved; as for the concrete-filled steel tubular column formed after concrete is poured into the steel tube, bonding force between the concrete and the steel tube can be increased through the truss structures; and under the action of the pressure and the bending moment, the web member ribs of the truss structures can promote cooperative work ofthe steel tube and the concrete so that the tube wall face of the steel tube can be effectively restrained from externally deforming, and the local flexural property of the tube wall of the steel tube is improved. Thus the wall thickness of the tube wall of the steel tube can be further decreased, and the purposes of saving materials and lowering the cost are achieved.
本发明涉及一种钢管混凝土柱，包括钢管及桁架结构，桁架结构设置于钢管的内壁上，桁架结构的腹杆筋呈“W”型弯折，腹杆筋为至少两个，至少两个腹杆筋的第一弯折部对应连接，腹杆筋的第二弯折部间隔设置在钢管的内壁上，避免单个腹杆筋相对于钢管的管壁弯折或倾斜，提高桁架结构在钢管的内壁上设置的稳定性。在钢管内浇注混凝土后形成的钢管混凝土柱，桁架结构可加大混凝土与钢管之间的粘结力。在承受压力、弯矩作用时，桁架结构的腹杆筋可以促进钢管及混凝土协同工作，能有效约束钢管的管壁面外变形，提高了钢管管壁局部屈曲性能，进而钢管的管壁的壁厚可进一步减薄，实现节约材料、降低成本的目的。
