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 third step to calculate an inclusive-type elastic local buckling yield strength and a non-inclusive-type elastic local buckling yield strength respectively based on values of parameters temporarily set by a second step; and a fourth step to compare the inclusive-type elastic local buckling yield strength and the non-inclusive-type elastic local buckling yield strength to select one of the deformation states. It is possible to select one deformation state that has high chance to occur between the inclusive type and the non-inclusive type in the condition with the values of the temporarily-set parameters. The design method comprises a fifth step to calculate the performance of the square steel pipe column reinforcement structure based on the elastic local buckling yield strength of one of the deformation states, and a sixth step to finalize parameters according to the temporarily-set values in the case the computed performance satisfies the required performance. Parameters satisfying the required performance with the selected deformation state can be easily determined.SELECTED DRAWING: Figure 16
