Abstract
The invention belongs to a building structure member in the technical field of building engineering, and particularly relates to a concrete-filled square steel tubular column with a built-in spiral stirrup. The concrete-filled square steel tubular column comprises a square steel tube, the spiral stirrup, a longitudinal reinforcement and core concrete, wherein the longitudinal reinforcement is arranged on the inner wall of the spiral stirrup to form a spiral reinforcement cage which is arranged in the center of the square steel tube, the core concrete is filled in the internal space of the square steel tube to form the concrete-filled steel tubular column with the built-in spiral stirrup. The concrete-filled steel tubular column with the built-in spiral stirrup has the advantages of being high in bearing capacity, good in ductility, excellent in anti-seismic property, simple in structure, simple and convenient to construct, and good in economy.
