RAM Structural System calculates k using the stiffness of the column and the stiffness of beams framing into the column only. The calculation excludes the stiffness of two-way decks that are connected to the column. If you deem it acceptable to exclude…

The fix was released in v17.01.00 and is included in the version that you are running. The change is documented in the v17.01.00 release notes, which can be reviewed using the link below. See "ACI 318 Moment Magnification" in the New Features and Enhancements…

Yes, that is correct. A manually calculated k that is greater than 1 should be assigned so that the slenderness thresholds in ACI 318-14 6.2.5 are calculated correctly. When calculating the non-sway moment magnifier to account for small p-delta effects…

If the supporting deck is 2-way, then it gets meshed with and will support the walls above. If the deck is one way then there needs to be a beam (or wall) below the walls above to work. See also: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki…
