To facilitate consideration of effective structural measures using structural analysis using the finite element method.SOLUTION: A design support method includes: a stiffness index calculation step of calculating a distribution of stiffness indexes on a model by performing structural analysis by the finite element method when a load is applied to a specific load point, for the model of a frame member having an inner part having a closed sectional structure with a sectional polygonal shape and an outer part cooperating with the inner part to form a closed sectional structure with a sectional polygonal shape; a division step of dividing the calculated stiffness indexes into a plurality of ranges; and a reinforcement part specifying step of specifying, as a reinforcement part to be reinforced of the frame member serving as the model, a portion in which the stiffness indexes are in different ranges for the inner part and the outer part when a cross section of the model is obtained.SELECTED DRAWING: Figure 8

    【課題】有限要素法を用いた構造解析を利用して、効果的な構造対策を検討しやすくする。【解決手段】断面多角形状の閉断面構造を有するインナー部とインナー部と協働して断面多角形状の閉断面構造を形成するアウター部とを有するフレーム部材のモデルに対して、特定負荷点に荷重をかけた際の、モデル上における剛性指標の分布を、有限要素法による構造解析を行うことで算出する剛性指標算出ステップと、算出された剛性指標を複数のレンジに分割する分割ステップと、モデルの横断面を取得したときに、インナー部とアウター部とで剛性指標が異なるレンジになっている部分を、モデルとなったフレーム部材の補強すべき補強部位として特定する補強部位特定ステップと、を含む。【選択図】図8
