I made a numerical model of a reinforced concrete frame in ANSYS APDL software in order to perform a PUSHOVER analysis, but the only experiment results that I got from the literature are obtained from a cyclic load experiment. However, the results are illustrated in terms of Base reaction versus roof displacement.
My question is, can I validate my numerical model with the envelope of the experimental cyclic results?
I apply the CESTAC method and the CADNA library to validate the results of numerical methods.
You sure can by using the envelope response of the cyclic test results.
Nowadays, a variety of pushover analysis methods have been developed, including Modal pushover, Adaptive pushover, and Cyclic pushover, in which some weaknesses of the conventional pushover method have been rectified. In the conventional pushover analysis method, the effects of cumulative growth of cracks are not considered on the reduction of strength and stiffness of RC members that occur during the earthquake or cyclic loading.
I think these papers will help you:

Yes you can validate the results with envelop of cyclic curve. However, numerical results are required in terms of lateral load versus roof displacement and not base shear. You may refer these papers:

You can do it by sure but there will be some differences since pushover analysis method is an an approximate analysis method
Please see my comment above. You can get a reliable comparison by comparing to teh envelop response. For example, check this paper out: "Enhancing Seismic Performance of Bridge Cap Beam-to-Column Joints Using Prestressing" at (pci.org)
