DESIGN METHOD FOR SQUARE STEEL PIPE COLUMN REINFORCEMENT STRUCTURE, AND SQUARE STEEL PIPE COLUMN REINFORCEMENT STRUCTURE
To provide an easy design method for a square steel pipe column reinforcement structure that can appropriately improve deformability, and a square steel pipe column reinforcement structure.SOLUTION: A design method for a square steel pipe column reinforcement structure of this invention comprises a second step that calculates an inclusive-type elastic local buckling yield strength based on specified required performance. It becomes possible, in terms of the deformation state of a square steel pipe column 1, to make a design such that an inclusive type deformation state capable of efficiently improving the deformability is made easy to occur. The design method comprises a third step that temporarily sets some of parameters relevant to a reinforcement material, and a fourth step that calculates conditions for other parameters relevant to the reinforcement material by using the calculated inclusive-type elastic local buckling yield strength and some temporarily-set parameters. By temporarily setting some of parameters relevant to the reinforcement material and, based on the temporary setting, calculating conditions for the rest of the parameters so that an inclusive-type elastic local buckling yield strength satisfying the required performance is materialized, parameters to satisfy the required performance can easily be determined.SELECTED DRAWING: Figure 17
