Bending Moments in Slabs (shells) using SAP2000

[dftucker]

Hello I have what seems to be an easy problem which I cannot figure out.

I want to analyze the bending moments in a slab supported on walls using SAP2000. I know that the slab should be modeled as a shell and that the edges should be fixed to represent the stiff walls. When I run my model and look at the analysis I cannot find an option which reports the bending moments in the shell (for both x and y directions). All I can find so far are wall reactions and the slab deflection.

Thanks for helping if you can!

Did you try to click the Display-> Show Forces/Stresse->Shell menu item?
Then you may choose the m11 and m22 options to see the resulting bending moments in the local 1 and 2 directions respectively.

Thank you very much, works perfectly.

I was doing exactly that, but had my component type set to "Shell Stresses" instead of "Resultant Forces".
Stupid mistake because moments are forces not stresses... thanks for the help!
