Are Structural Rotations and Rotational Displacements in Radians or Degrees?


Both are in Radians.

Structural Rotations:
See Commands Reference> D Commands> D command in Notes: "Structural rotations should be input in radians"

Rotational Displacements:
Element Reference> Chapter 2. General Element Features 2.2.1. Nodal Solution
"Rotational displacements (ROTX, ROTY, ROTZ) are output in radians"
