STAAD Output

How to use in STAAD:

  1. Open STAAD.Pro → go to General > Load & Definition.
  2. Open the Editor (Commands) and navigate to the load definition area.
  3. Paste the block above between other load commands. Adjust envelope numbering/names if needed.
  4. Save and run analysis. Use the Envelope results for design checks.

Tip: Dragging a combination does not remove it from the source list, so you can include the same combination in multiple envelopes if your workflow needs it.
