摘要：
When the shape of the cross-section is changed from a square to an octagon by chamfering the four corners of the square, the octagonal hollow cross-section is not only permited the use of thin plate elements, but also suppressed local buckling. But there are few studies addressing octagonal members, and it is not sufficiently clear whether and how the cross-sectional shape affects their buckling behavior. This study aims to show how the cross-sectional shape affects elastic buckling strength and suggests a method to evaluate maximam strength and plastic deformation capacity of octagonal hollow cross-section member. © 2021 Architectural Institute of Japan.
