multi-element beam with pinned ends

aero_guy

Hello,

I am working on setting up a truss frame model.  The model consists of beam elements only.

I want some of the beams to have "welded" connections, which is the beam element default, and I want some members to have pinned joints.  I know about using the "truss" checkbox in beam elements to make pinned ends on a single beam element.  This works fine if I join the connection points of my truss members by one single element.  If I subdivide the element, each element then gets pinned ends, which acts like a piece of rope then.

Is there a way to make one end of the pinned, and the other fixed?

Thank you.

This is what flexible joint on beam under Loads & Constraints is for. It can be a bit tricky to select the beam end faces it uses, so here's an extract from the next version's manual showing how.

Thank you Victor.  That is most helpful.

In order to select the face of some of the beam elements that were located at nodes with many intersecting beams, I found it easier to put the "pinned" beams on a separate component, so I can hide everything else and freely access the elements of interest.

Thanks again.
