I am designing a fire wall in RCDC. The model imported from staad is attached. I calculated the effective length factor and applied in staad. Now when I import this model in RCDC it does not take the effective length factor from STAAD.Pro. I tried to put the effective length factor manually but RCDC has limited the value to 5, while my effective length factors are coming out to be greater than 5. How do I apply this factor in RCDC as I need to design these columns for crack width check?
I also tried to remove the effective length factor from STAAD.Pro model and apply the slenderness moment (calculated by STAAD.Pro in previous model) at top nodes in each column so I could design for slenderness in RCDC but Staad analysis shows reduced moments about Z axis and higher momKEC-DE04-PS-MBCK-DGN-7011_R0.4.stdKEC-DE04-PS-MBCK-DGN-7011_R0.5_SlenderMoment02.stdents about Y axis of column. It is transferring the moment as torsional moment to beams. How to fix this?
