Title:
COMPUTATION DEVICE, FACILITY MANAGEMENT METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/079433
Kind Code:
A1
Abstract:
The purpose of this invention is to provide a computation device, facility management method, and program that make it possible to acquire the current tension acting on an outdoor structure in a short period of time and assess the yield strength of the structure. A computation device according to this invention uses formula C1 to calculate the sag and pole-to-pole distance of a cable from three-dimensional model data for the cable and uses formula C2 (without wind) or formula C4 (with wind) to calculate the tension of each cable between poles from the sag, pole-to-pole distance, and cable weight per unit length thereof. Further, this computation device uses formula C3 to calculate a combined load obtained by converting the tension and a pole accessory load to a load at a given position on the pole.
