How to transfer forces from fixed beam to weld providing that fixity?
How to transfer forces from fixed beam to weld providing that fixity?
(OP)
I have modeled a beam as fixed-fixed. The reaction forces are -1494 lb.ft and 761 lb (vertical). There is no horizontal reaction.

Now I know this beam is welded to another element. I am trying to design the weld for the necessary forces. How do I transfer the reaction forces at the fixed end to the weld? Should I invert the directions of the reactions or should I preserve the same directions?

For a symmetric connection (as described above) and no axial force in the beam, the magnitude of your stresses are the same at both ends of the weld, so the sign convention won't matter.

You should also check the coped section for the loads. Since there is "only" the stem of the tee at play at the end of the beam, it will need to resist ll the loads.

From the standpoint of LTB, I think I would be concerned about the lack of lateral support for the tee flange at each end.
I would try to avoid the cope if possible.
