The pupose of this study was to propose a method which estimates resultant force and moment from the shape of deformed pole based on a static equilibrium equation. The force and moment were assumed to be exerted at the middle point of both hands on the pole. The pole was modelled as a series of 11 rigid segments connecting its adjacent segment via a virtual rotational joint with a rotational spring component. The stiffness of the spring was identified from a static load test. The resultant mid-grip force and moment were calculated from a static force-moment equilibrium equation. The results indicate that the kinetic values obtained by the proposed method show similar values reported in the previous study which utilized a force plate.
