1. Component Forces
When the mouse is not hovering over the Resultant Forces Graph, the component forces will be the the components that will create the maximum (or worst case) Total Force.
When the mouse is hovering over the Resultant Forces Graph, the component forces will be the display force components create by the specific wind direction shown by the (11)Wind Source.
In the case where a stay is present, the maximum pole forces shown will be the worst case on the pole when the stay is present. That is the scenario where the direction of wind that is in the same direction of the horizontal tension component of the stay. Therefore in this scenario the stay does not take any force, so Total excluding Stays and Total Force is the same.
Note that the scenario for worst case Stay Tension, will be different to worst case Total Force on pole, as shown by the Wind Source of each component.
Tension Conductor force in the axial direction along the conductor
Transverse Conductor force perpendicular to the conductor span due to wind
Pole Wind Wind load on pole
Total excluding stays Total tip load forces, excluding the influence of any stays. It is calculated from the vector addition of Tension, Transverse and Pole Wind forces.
Total Force Total tip load forces, including the influence of any stays (if any). It is calculated from the vector addition of Tension, Transverse, Pole Wind and Stay forces.
2. Base Forces
The calculated force loadings without factors applied.
3. Limit State Multiplier
Limit State factor multiplier, as per input in Environments.
4. Limit State Result
Final limit state value, which is (2) Base Forces x (3) Limit State Multiplier.
5. Force Angle
Angle of the resultant force in degrees. It is the angle component of the force vector.
6. Pole
Details of pole being examined. The pole details can be changed here by clicking on pole name.
7. Base Pole Strength
Ultimate breaking strength of the pole.
8. Working Strength of Pole
This is the (7) Base Pole Strength multiplied by the pole strength reduction factor as specified in Environments.
9. Pass/Fail State of Pole
PASS will be shown when (1)Total Force <= (8) Working Strength of Pole
FAIL will be shown in all other scenarios
10. Add Opposing Stay
Click this to add a stay directly in the opposite direction as the angle of the Total Forces
11. Wind Source
The direction of wind that has generated the values shown in the (1) Forces column.
Stay Force Details
12. Tip Load Component Force
When the mouse is not hovering over the Resultant Forces Graph, the component forces will be the the components that will create the maximum (or worst case) Stay Tension.
When the mouse is hovering over the Resultant Forces Graph, the component forces will be the display force components create by the specific wind direction shown by the (11)Wind Source.
Note that the scenario for worst case Stay Tension, will be different to worst case Total Force on pole, as shown by the Wind Source of each component.
Tipload This is the horizontal tipload in (1)Total Force excluding stays. It is the horizontal force required to be countered by the stay
Countered The horizontal tension on stay at pole top to counter the Tipload
At Stay Height The horizontal tension on stay at the attach height of stay
Stay Tension Tension on stay cable, along the axis of the stay
13. Base Stay Forces
The calculated force/tension loadings without factors applied.
14. Stay Tension Limit State Result
Tipload This will be the same Limit States Result of (1)Total Force excluding stays.
Countered The limit state result will be the same as Tipload as this is the derived force required to counter the tip load.
At Stay Height The horizontal tension on stay at the attach height of stay.
Stay Tension Tension on stay cable, along the axis of the stay.
15. Limit State of Stay
Limit state factor applied to the ultimate cable break load of stay.
