Is there any way to prove/verify that a non-moment connection (in reality) in a (unbraced) truss end portal acts as a moment connection (as modeled)? In order for the model to be stable, I either had to 1) make the top chord (strut/beam) to portal leg connections moment connections, or 2) make the support conditions at the portal legs fixed. I went with option 1 since the truss is mounted on a steel bent, and not directly to a rigid concrete foundation.
