Stiffener to skin connection forces

Stiffener to skin connection forces

Stiffener to skin connection forces

(OP)
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

RE: Stiffener to skin connection forces

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