Erection Engineering — Temporary Guy Tension
Temporary Guy Tension for steel erection field engineering.
Guys resist wind with the cosine and punish the column with the sine — steep guys nearly double the axial kick for the same wind. Temporary bracing design is the erection engineer's signature item; this is the geometry behind it.
Formula
Note: Erection-planning estimate only. Member weights, connection capacities and tolerances for execution must come from the issued drawings, the EOR and the erection engineer — never from a generic calculator.

About Erection Engineering — Temporary Guy Tension
Erection Engineering — Temporary Guy Tension computes the governing relationship T = F/(cosθ·n); vertical kick = T·sinθ live as you type. Guys resist wind with the cosine and punish the column with the sine — steep guys nearly double the axial kick for the same wind. Temporary bracing design is the erection engineer's signature item; this is the geometry behind it. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Erection Engineering — Temporary Guy Tension
- 1Enter your values — Wind force at top, Guy angle from horizontal, Effective guys windward (sensible defaults are pre-filled).
- 2Read the live results: Guy tension, Added column compression.
- 3Check the "with your numbers" line to see T = F/(cosθ·n); vertical kick = T·sinθ substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
