Abstract

Un miembro estructural 10 que incluye una estructura de sección transversal cerrada que tiene un miembro de sombrero 1 y una placa de cierre 2 y un miembro de refuerzo (miembro de refuerzo complementario ("SSM")) 4. El miembro de sombrero 1 incluye dos paredes laterales 11 y 12, cada una de las cuales, incluye una porción de resistencia alta 11A, 12A con un límite de elasticidad no menor que 500 MPa y porciones de resistencia baja 11B, 12B con un límite de elasticidad de 60 a 85 % del límite de elasticidad de la porción de resistencia alta. Tal como se determina a lo largo de la dirección de extensión de las crestas 123 del miembro de sombrero, ambos extremos del miembro de refuerzo 4 se superponen a las porciones de resistencia alta 11A y 12B de las paredes laterales 11 y 12. Adyacentes a al menos uno de los dos extremos del miembro de refuerzo 4, el borde entre las porciones de resistencia alta 11A y 12A y las porciones de resistencia baja 11B y 12B se colocan en una región que comienza en una posición de 1/3 y termina en una posición de 3/2 de la altura H de la pared lateral 11, distante de ese extremo del miembro de refuerzo 4, tal como se determina a lo largo de la dirección de extensión de las crestas 123, lejos del miembro de refuerzo 4.
