Abstract
(EN)

A member has a transverse cross section that includes a top sheet, upper ridgelines, vertical walls, lower ridgelines, and floor flanges and includes, on at least one end portions in the extending directions of the upper ridgelines, a top sheet flange via a top sheet ridgeline and vertical wall flanges via vertical wall ridgelines, in which the vertical wall flange and the floor flange are continuous. In end portions of the upper ridgelines and the lower ridgelines, the sum totalΣR of the radii of curvature of corner portions of the vertical walls and the sum totalΣL of the widths of the top sheet and the vertical walls in an end portion of the member have the relation ofΣR/ΣL≤0.13.
