Dear cagri kirt,

You need to request Harmonic stress output as shown in attached image.

The "Equivalent Real Harmonic Stress" and "Equivalent of Real Harmonic Stress" both are computed from components of "Real Comp of Harmonic Stress".

You will notice these two output i.e "equivalent" and "equivalent of " is available for result type such as stress , strain etc..

The difference is explained in below article,

I read the article but still i dont follow the connection between equivalent real harmonic stress and equivalent image harmonic stress diffrence. what u mean is real harmonic stress come from integration calculation and image harmonic stress comes from extrapolation.

No. The article talks about difference between "equivalent of " and "equivalent " results for example, equivalent stress and equivalent of stress.

Real and Imaginary components are available if you invoke damping.

Vol. A -Chapter 5 - Harmonic Response section has more details.
