Reply To: Solution combination give me a lower stress than the static case one

Yes, I think linear is a better choice.  I agree with everything you say above, but I wasn't aware that a Solution Combination would allow you to specify a phase angle for the harmonic results.  If it does, then linear is especially good.  SRSS is necessary when combining results that have lost their sign such as Response Spectrum and Random Vibration results, but you don't have that.
