When can we use this option "Frame stability considered in analysis" in RAM integrated in Staad Pro?

In Ram Connection? I like to align that with the Ram Frame assumption explained above. For anything less than a full 100% Rigid End Zone, panel shear deformation was considered.

The Connection help confirms:

Flag needed in the Panel-zone web shear verification. If it is true, the effect of panel-zone deformation on frame stability was considered in the analysis of the structure. Otherwise, it is false and the deformation was not considered.

Hi Karl,

Could you please elaborate on when to check "Frame stability considered in analysis" option? Thanks!

Best

Section 3.3.3 in the RAM Frame Steel Post-Processors Manual addresses this question. An excerpt follows:

"Two different equation sets are presented in AISC when performing panel zone checks. The first set (equations LRFD 3rd: K1-9, K1-10 / AISC 360: J10-9, J10-10) is applicable when panel-zone deformation is not considered in the analysis. The second set (LRFD 3rd: K1-11, K1-12 / AISC 360: J10-11, J10-12) is applicable where panel-zone deformation is considered in the analysis. RAM Frame looks at the rigid end factor to determine into which group the structure falls. If full rigid ends are used then RAM Frame assumes that the Panel Zone is not considered in the analysis. If any value less than the full rigid end zone is used, then the program assumes that the panel zone is considered in the analysis and equations LRFD 3rd: K1-11, K1-12 or AISC 360: J10-11, J10-12 are used."
