摘要
A method for evaluating local buckling performance of a steel pipe includes obtaining a stress-strain relationship of a material having a yield plateau in the stress-strain relationship; determining the comparison of a starting strain of strain-hardening in the stress-strain relationship obtained and a critical strain of the steel pipe; and evaluating that the steel pipe has a possibility of being applied to a structure that requires plastic design when the critical strain is determined to be larger than the starting strain and evaluating that the steel pipe has no possibility of being applied to a structure that requires plastic design when the critical strain is determined to be not larger than the starting strain.
