The problem with the bonded contact is not really related to rotation but to the bearing pressure distribution. Rather than bearing on say half of the pin/bush, bonded contact will distribute the load path round the pin circumference. This will affect the pin stress and also the stresses in the...
If it's rotation of the pin that's the problem try adding a rotational constraint to one end (use a remote constraint acting over the end face but applied to a point in the centre of the face in rotation about x-axis). It's realistic as presumably the pin is (or could be considered to be)...
I would have thought there's not much point using large displacement analysis and non-linear materials if you are incorrectly applying bonded contact at the pin/bush interface. You should be able to prevent pin rotation in your model in a realistic way (using symmetry, applying friction or...

Lloyd's refer to this specifically as the "slewing ring bolting" calculation, which I guess might also be called the turntable ring.
The calculation is derived by taking the bolts as distributed around their pcd and taking the tensile/compressive and bending on the resulting tube.

This calculation is for a crane slewing ring, so naturally the direct load is compressive. In the general case the sign would reverse if the load on the group is tensile.

Hi
The other way round this would be to set up all the combined load cases and use Parameters to input the factored loads to each. Parameters can be read in from your external data.

Hi
If all load cases are linear, just Right Mouse on Model > Insert > Solution Combination. Then Add to set your coefficients for each basic case. You can then copy the Solution Combination and go into it to edit coefficients as required.

One option would be to define remote constraints about the centroid of the support patch. These allow output of the reaction forces and moments which could be used to calculate the (triangular) pressure distribution.
Alternatively, set up contacts between the hull and support frame and...
