Stiffener to skin connection forces

[trainguy]

Hi guys.

In a stressed skin structure (passenger railcar)I need to size welded connections of stiffeners to the skin they're welded to, using results from a beam/plate analysis done with Femap and NeiNastran.

I suspect I need to use Grid Point Force balance, then only extract nodal forces applied by the shell elements to the beam elements. How do I actually do this in FEMAP?

Any other ideas that would make this less painful? Is there any output vector that does this?

Thanks,

tg

i'd look at the change in endload of the stringer as being the load sheared into the stringer over the length considered.
