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
