This section covers a tangent pole line with equal length spans, in a typical joint-use configuration. No load nonlinearity is considered.



Pole configurations are 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, in the perpendicular direction.


Tests:

  1. Poles
    1. 45-3 WRC pole
    2. 45 ft Stresscrete class D
    3. 45ft IUSI GX5
    4. 45ft RS-Poles model RSP-45-123
  2. Span lengths
    1. 30m Urban configuration
    2. 40m Urban configuration
    3. 50m Urban configuration
    4. 60m Urban configuration
    5. 70m Rural configuration
    6. 80m Rural configuration
  3. Analysis methods
    1. Linear
    2. 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 at groundline
    • Forces & moments (Fx,Fy,Fz,Mx,My,Mz)
    • Stress value and % utilization
  • Pole top deflections
    • Lateral X dir
    • Lateral Z dir
