Unlevel Spans
This section covers unlevel equal spans in a typical joint-use configuration. No load nonlinearity is considered.
This is a Rural configuration as described in the start of this section. Wires will be exposed to 400 Pascals of wind pressure and 12.5mm of radial ice accretion at -20C, applied perpendicular to the line.

- Analysis methods
- Linear
- Geometric Nonlinear
Pole types may be adjusted to higher strength poles after/when the first set of results come in, if most results are highly overloaded or unstable. The desire is to evaluate real scenarios up to their limit and a little beyond.
Results to be recorded:
- Pole results groundline
- Forces & moments (Fx,Fy,Fz,Mx,My,Mz)
- Stress value and % utilization
- Pole top deflections
- Lateral X dir
- Lateral Z dir
