releases

I just finsihed my model, and somthing doesn't look right. When I'm looking at the moment diagrams it doesn't look right. So I believe there is something wrong with the releases. I don't understand how to set releases, please help

I've tried to send the file via ftp now, believe it worked, but not sure since I haven't used ftp before:)

I am afraid you have to explain what you see \ what you expect with more details.

I do not see any problem with releases. I found them on just only 3 bars:

f.ex: The two beams in the attached pictures are identical, but the moment diagrams are not identical.

it seems you have used member offsets for the beams on the panel edge, this will give the "saw tooth" bending moment shape.  

 

but why they are different shapes you need to look at the applied loadings?

The two beams are carrying the same loads. (the slab and the live load applied to the slab)

It is caused by model (geometrical inaccuracies).

Take a look below:

These inaccuracies  do not cause these problems but may give you wrong results:

These nodes makes them. Nodes in positions marked by green rectangles should meet in \ as a one node at the bottom of these short roof columns.

should it be supports under the entire bottom slab, or just on the edge and under the wall?

If under the whole slab the question is why  \ what for to model this slab? IN such case all results will be 0 in such slab.

I guess you are looking for soil elastic support for plate.
