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.

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
