To reduce a calculation load.SOLUTION: A load calculation device 170 comprises: a coefficient storage unit 172 which, when a unit load is applied in an axial direction of one axis of three axes perpendicular to one another to a concentrated load point in an object member, stores an internal load applied to an object point in the object member as a first coefficient associated with the concentrated load point and the object point, and when a unit moment around an axial direction of one axis of three axes is applied to the concentrated load point, stores an internal load applied to the object point as a second coefficient associated with the concentrated load point and the object point; a replacement derivation unit 176 which derives a replacement load and a replacement moment obtained by replacing an external load applied to the object member with six force components applied to the concentrated load point; and an internal load derivation unit 178 which, when an external load is applied to the object member, derives an internal load applied to any object point as the sum of the product of the first coefficient and the replacement load and the product of the second coefficient and the replacement moment.SELECTED DRAWING: Figure 10
【課題】計算負荷を軽減する。【解決手段】荷重計算装置１７０は、対象部材における集中荷重点に、互いに垂直な３軸のうちの１軸の軸方向に単位荷重が作用したとき、対象部材における対象点に作用する内部荷重を、集中荷重点および対象点に関連付けた第１係数として記憶し、集中荷重点に３軸のうちの１軸の軸方向周りの単位モーメントが作用したとき、対象点に作用する内部荷重を、集中荷重点および対象点に関連付けた第２係数として記憶する係数記憶部１７２と、対象部材に作用する外部荷重を、集中荷重点に作用する６分力に置換した置換荷重および置換モーメントを導出する置換導出部１７６と、対象部材に外部荷重が作用したとき、任意の対象点に作用する内部荷重を、第１係数と置換荷重の積、および、第２係数と置換モーメントの積の和として導出する内部荷重導出部１７８と、を備える。【選択図】図１０
