Reservoir - Robot Structural Analysis

[ashley_calleja]

Good Morning, 

I am new to Robot Structural Analysis and I have some queries I would like to discuss. I am designing a Reservoir Structure with a beam-column system and a masonry wall on the perimeter. I have modelled the reservoir, however I have these issues:

1) How can I input on the model that my perimeter walls are brick walls?
2) As seen from the attached model, I have high moment concentration where the beam and wall interact. As a consequence, I have a high amount of steel required on the edges of the slab. How can I solve this please?
3) I would like to have the wall and slab as 2 separate elements, such that the slab has some freedom of movement and not act monolithic with the wall. 

Thanks in advance.

Any reply to this please?

Your model has no slab at the bottom/support level . Your walls have perpendicular support on both local directions Uz+ and Uz- (foundation elasticity). It should have uplift on Uz- direction.
