load rating custom made lifting piece
(OP)
I'm trying to analyze a custom made "lifting cap" to find the safe working load.
This consists of a 16" diameter steel caisson 12" long with 0.565" thick walls welded to a 1" thick plate (at bottom). The caisson is threaded at the top and will be attached to a rig. The eyelet is 2 inches thick and welded to 1" plate at bottom. Since it should all be loaded in tension (downward) I'm expecting the weak part to be the 1" plate. But I don't know how to check a circular plate for bending with a distributed line load... can anyone help?

Roark may have a load case resembling that, but I don't remember seeing one before.

Table 9.1 case 1 or
Table 9.2 case 4 and case 15(changing sign)
Furthermore for the eyelet : I should make a slot on the plate 1" thick so to insert the eyelet plate and weld on both sides of the plate 1" thick
