The steel tube of the solid steel tube concrete is positioned at the periphery of the section, the stable bearing capacity of the steel tube is easy to lose under the action of fire, and the hollow interlayer steel tube concrete giant column has good protection effect on the inner tube due to the wrapping effect of the concrete on the inner tube, so that the stable bearing capacity of the inner tube is not lost for a long time.
Compared with a shear wall core tube, the hollow sandwich steel tube concrete giant column has the advantages that the core concrete is in a three-way compression state due to the constraint effect of the steel tube and the bidirectional opposite-pulling stirrups on the concrete, so that the rigidity and the lateral force resistance of the giant column can be increased; the high-strength concrete filled in and the bidirectional opposite-pulling stirrup can prevent local buckling, so that deformation is reduced, and the stability and the ductility of the steel pipe are enhanced.
