Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a reinforcing member and a deciding method of this shape, with which the lightening and the reducing of material cost are obtd. by optimizing the shape of the reinforcing member. SOLUTION: The reinforcing member 3 formed so that plastic moment needed in the min. limit to reinforce a shape material 1 according to the height L2 of the reinforcing member 3. In this way, the shape of the reinforcing member 3 is formed as the shape provided with a curving part and the strength needed in the min. limit to the reinforcement is provided and the excessive reinforcing portion is saved. Therefore, the lightening of the reinforcing member 3 and the reducing of the material cost can be obtd. |
