Quick Pole Verification

When calculating the assumed loads to be applied to a structure for analysis, weather load cases that involve wind must be evaluated repetitively for different possible wind directions. Each wind direction considered is a separate structural analysis for which its results need to be scanned to detect the worst condition for the structure's members (e.g. pole, guys, anchors, cross braces…) and foundation. Given that span attachments can be at any angle attached to the structure and the wind can come from any angle, it is important that line design software be evaluated for its ability to calculate the span attachment's assumed load to be applied to the structure, for any wind or span attachment angle combination.

Most Sag & Tension calculations assume the wind blows against the span attachment at right angles (90 degrees) to the line. However, much more exact figures are required for accurate structural analysis. For this reason a specific test was developed to compare Quick Pole's assumed load calculation against that of PLS-CADD for wind incidence angles from 90 degrees to zero.

The wire tested was 3/0 ACSR Pigeon tensioned to 6360N @10C with the worst load case as CSA Heavy. Below shows a plot of individual calculations for each software, indicating an extremely close match.
