QUESTION: What is the significance of the Post-tensioned check box on the Geometry tab screen in LRFD mode?

ANSWER:

Depending on whether this option is checked or not, the live load distribution factor is computed based on two options, respectively:

  1. Beams sufficiently connected to act as a unit.

  2. Connected only enough to prevent relative vertical displacement at the interface (for more information see LRFD table 4.6.2.2.2b-1).
