making simply supported span

[Anonymous]

does robot consider the beam in this structure as simply supported beam?

I'm not getting the bending moment as it's a simply supported beam WL2/8 = 4.5KNm

You need to define pinned connections among bars and "disregard" stiffness of the slab.

Do I go to releases diaglog and make the beam pinned-pinned ?

 how can I "disregard" stiffness of the slab.

As by default all connections among bar elements are assumed as rigid you need to assign pinned-pinned releases to the beams that are not intended to transfer bending moments at their connections with columns.

You may define it as a cladding (surface intended for load distribution only).

Thank you that helped

So the cladding if I'm corred is the slab for example will distribute the load, if this option is not applied then the slab will carry some load?

In case you want to include slab as a structural part of the model you need to mesh it. To have a similar behaviour as for the cladding you need make it to work in one direction only.

Hi

I created a new thickness as you said and released supports for beam and slab and bending moment My is excactly as excpected

but I have two question:

1) Why I'm getting the warrning (Separate structure)

2) Is it possible to view the distributed load on the beam? I can view the shear force and make a forumla 2V/L to get the distributed load but it there a direct way to do that?

1.I think.Robot show separate structure due to structure not connect as picture.

2.robot can.you can check box as picture.

Thank you I am now able to see the loads generated by calculation

but why the columns are not connected (I'm getting a value of 10KN for Fx), the way I used to draw them : Geomerty >> Columns >> height: 3.5 (down), and click on the location of column

The warning is displayed as both frames are not connected neither by other bar elements nor surface elements generated during meshing of a panel.

How can avoid that ?

[Artur.Kosakowski]

The display of the warning for such model is as designed. Just ignore it.
