problem with ladder analysis

[cesuray]

When I do a ladder analysis, I get an error that says the number of modes used in dynamic analysis is insufficient, how can I fix it?

Stair analysis is done with the ladder analysis button. The message about dynamic analysis can only appear when you perform Analysis+Reinforced Concrete. However, the mode failure message may be due to incorrect rendering of the frame model. It is useful to see your data for a more precise answer.
