Beam forces in ETABS vs. SAFE
Beam forces in ETABS vs. SAFE
(OP)
I've calculate a structure in Etabs, only for gravitational loads and then I export the first storey in SAFE to calculate both the beam and slab forces.
My question is WHY for the same beam and the same combination the shear force at the end of the beam is 150kN (ETABS) and 100kN (SAFE).
What i'm doing wrong?
Note: Manually calculations is all most equal with the results from ETABS.
Thanks in advance!

If slab is modeled as membrane (no out-of-plane stiffness), I think the results will match.
It's no trick to get the answers when you have all the data. The trick is to get the answers when you only have half the data and half that is wrong and you don't know which half - LORD KELVIN

Lebron 1987,
After you export your floor from ETABS to SAFE, assign all bending modifiers as 0.0001 in SAFE in "Assign" menu and uncheck the "thick plate" option in slab properties. Now run your SAFE model and compare your beam shear in ETABS and SAFE, these will match.

@nonlinearer: I will try what you say
Thanks for your answers!
