Hey, I am just wondering why the circled areas shown in the image don’t have 0 moment, im wondering is it a joint issue, or the fact that multiple members meet at the nodes that it is assuming an element of rigidity at that joint. Im a student so not 100% sure how it is supposed to look, but i am assuming it should be 0 moment as it is cantilevered from the column.

I have attached my script, and would really appreciate it if someone could have a quick look into it to see!

Deat @Jack_Lawless,
when defining joints one needs to specify also the DOFs which should be opened:

In the above definition four joints are active (the white circles) which open the DOF corresponding to My.
