Hing Conncetion

[pooyantt]

Hello
I want to model the frame below in ANSYS, my problem is modeling the connections between elements.
I used BEAM3 for element type which default connection type between two elements is rigid.
As you see the middle connection has three elements joined.
My aim is the connection between 1 & 2 be rigid and 3 be hinged.
How can I model it?
Can I use CP (Coupling feature)?

The easiest way is to release the rotational DOF at one end of the element, but unfortunately BEAM3 doesn't allow this (see the KEYOPTs in the Manual). BEAM44 will allow you to do this but you'll need to make the appropriate modelling changes to incorporate this 3D element.

How about CPINTF command in ANSYS GUI?
