I am attempting to use the Joint Code check functionality of RAM Frame, and am a bit confused about implemenation, so any help would be appreciated.
From my readings of the Frame anlysis, and steel post-processor manuals/technical manuals, I though I had deduced the following:
1-Ignoring rigid end zones (in the frame/general criteria) would ignore panel zone deformation, and therefore frame stability has not been considered so AISC360-05 eqn. J10-9 would be used for panel zone shear
2a-Including effects at 0% reduction would not consider deformation and be in the same insctance as ignoring the effects.
2b-Including effects at 100% would consider deformation, and therefore J10-11 should be used.
This does not appear to be the correct understanding however, as situations 1 and 2b produce the same effect. Does anyone have any more info about this code interpretation?
Thanks.
The result sounds correct to me.
In other words, if you ignore rigid end zones (case 1), then a centerline analysis is performed, which is equivalent to assuming that panel zone deformations were considered in the analysis. Similarly, if you use a partial rigid end zone, one with some reduction (case 2b), at least some panel zone deformation was considered in the analysis. So for either case the program evaluates equations J10-11 and J10-12 with ASD 360-05 code.
It is only when a full, unreduced rigid end zone in considered (case 2a) that we can say panel zone deformations were not considered in the analysis. Here the program checks J10-9 and J10-10.
