Abstract
A method for testing poles (1) including the steps of applying a first load to a pole (1), measuring the movement of the pole (1), at least partially de-loading the pole (1) to a second load, measuring the movement of the pole (1), and using the change in the movement measurements under the respective loads to calculate the pole (1) stiffness.
Claims8
A method for testing above-ground poles including the steps of
- a. applying a first load to an above-ground pole,
- b. measuring the movement of the pole under the first load,
- c. at least partially de-loading the pole to a second load,
- d. measuring the movement of the pole under the second load, and
- e. using the change in the movement measurements from the first load and the second load to calculate the pole stiffness.

- b. measuring the movement of the pole under the first load,
- c. at least partially de-loading the pole to a second load,
- d. measuring the movement of the pole under the second load, and
- e. using the change in the movement measurements from the first load and the second load to calculate the pole stiffness,
- wherein the second load is calculated dependent upon the soil type.
