Minimal internal bending moments

Hey community

I'm quite new to using robot, and just trying to get the bending moment on the roof, with a superficial load of 100kgf/cm2 and the load being distributed as such

However, I don't understand why the moments are so low in the roof itself and do not match hand calcs. I have not assigned any supports to the upper edges of the walls because that makes the moments 0

This is just with the live load and no combinations as I'm just trying to get the hang of it, I am aware the moments are in the kNm/m units, but they are still pretty low

Any help is appreciated, thank you!

Accepted solution

You have to assign shell as the calculation model ,so you can have finite element (analytical) transfer of loads.

With the simplified method you will get wrong results .
