    Abstract: The present invention has an object of providing an arithmetic apparatus, a facility management method, and a program that make it possible to acquire current tension applied to outdoor structures in a short period of time and make a bearing determination. The arithmetic apparatus according to the present invention calculates the dip degree of a cable and a distance between poles from the 3D model data of the cable according to Math. C1 and calculates the tension of each cable between the poles from the dip degree, the distance between the poles, and the weight of the cable per unit length according to Math. C2 (when no wind blows) or Math. C4 (when wind blows). Further, the arithmetic apparatus according to the present invention calculates a combined load obtained by converting the tension and the load of the accessory of the poles into an arbitrary position on the poles according to Math.
