Abstract

The invention discloses a hollow steel pipe-reinforced concrete superimposed member which belongs to the technical field of civil structural engineering. The superimposed member is formed by external reinforced concrete wrapping internal steel pipes; the superimposed member is a novel steel pipe concrete superimposed member of which the internal steel pipes are not filled with concrete; and the external layer uses the reinforced concrete, and the internal layer uses common steel pipes. The longitudinal bars and the concrete are on the same level with the end surface of the internal steel pipes, and the sectional geometrical center of the reinforced concrete on the external layer is coincident with that of the internal steel pipes on the internal layer. The reinforced concrete on the external layer and the internal steel pipes on the internal layer respectively use circles, round ends, ellipse, polygons or other sectional shapes. The invention has the advantages in common internal steel pipe concrete superimposed members, greatly reduces the structure dead weight, enhances the bending rigidity of the structure, fully displays the functions of the material, saves the structural cost and enhances the anti-seismic performance and the fireproof performance. The invention can be widely used as large-diameter columns in bridge piers and buildings, and column members in other relevant high buildings.
