Abstract
(EN)
To provide a member that exhibits high load resistance and rigidity when connected to another member. A member 1 has a transverse cross- section that includes a top plate 2, top ridgelines 4, verticalwalls 3, bottom ridgelines 5, and floor flanges 9. The member 1 has, at least one end thereof in an extension direction of the top ridgelines 4, a top plate flange 11 connected via a top plate ridgeline 6 and a vertical wall flange 10 connected via a vertical wall ridgeline 7. The vertical wall flange 10 and the floor flanges 9 are continuous with each other. The relation [sigma]R/[sigma]L <= 0.13 holds true for the member 1, where [sigma]R is the sum of radii of curvature of corner portions of the vertical walls at ends of the top ridgelines 4 and the bottom ridgelines 5, and [sigma]L is thesum of widths of the top plate 2 and the vertical walls 3 at an end of the member. The member 1 is manufactured through a first step of manufacturing an intermediate formed article 27 that is provided with at least flange ridgelines 8 by subjecting a blank 26 to press forming and then shrinkage flange forming the flange ridgelines 8, and a second step of subjecting the intermediate formed article27 to press forming to thereby manufacture the member 1.
