hi,
I am building a frame with 5 bays and 6 oppenings which has a truss roof system.
I have introduced the trusses using the library option, and edited them to my conformation.
I think i am doing something wrong, because when i load the truss element I get relatively large bending moments in the bars, also in nodes, ... and what i thing is a big axial force .
My question is if i need to set some releases for the bars, or if the current approach is the correct one.
The project is for my bachelors degree.
I have attached the project file bellow,loaded on 2 frames(just for test pupose)
Thank you in advance,
Dan,Suciu

At the moment you have a kind of portal action happening (ie trusses are transferring moment into the columns).
Attached is file with truss ends pinned.
I only pinned trusses in the X direction. You need to go through and do the ones in the Y direction too.
