Quick Pole Verification

This Nonlinear method captures the changes in the magnitude and angle of the applied loads as the pole deflects. In accordance with popular codes, all other poles are assumed to remain stationary. There are two main scenarios where this additional methodology greatly helps to model the structures more accurately:

1. The balancing of inline tensions. Very common in scenarios where the span length on one side of the pole is much different than the other.
2. The recognition that wire attachments can also handle some loads that the pole does not need to address all by itself. A common scenario is where two relatively balanced lines attached to a pole cross each other at 90 degrees and the wires can be shown to help support the lateral wind load.

This is an improvement over just doing a Geometric Nonlinear analysis as it more completely models how the pole would actually behave with the attached wires. If a software tool cannot address Attachment Load Nonlinearity, they should note this in their compliance matrix.

The following tests are suggested to assess the Inline Tension situation:

1. Use 40 foot class 4 and 1 poles
2. Attach one medium size wire at two feet from the top of the pole.
3. Assume the span lengths are 40 meters and 60 meters.
4. Calculate the final tensions of the wires on both sides of the pole, plus the pole top deflection and Groundline stresses.
5. No storm loads

The following tests are suggested to assess the Wire Attachments carrying load situation:

1. Use 40 ft class 4 and 1 poles
2. Attach one medium size wire at two feet from the top of the pole with an average span length of 60 meters.
3. Place another wire attachment at the same height and crossing the previous at 90 degrees.
4. Apply horizontal load in the direction of the crossed wire with a magnitude of 3000 Newtons to simulate wind load.
5. Calculate the final tensions of the wires in all directions, plus the pole top deflections.
6. ½" ice and -20C storm loads, no wind
