Curious: What other fields use such pushover analysis besides designing
of civil structures?
If you're talking about true ultimate strength analysis, it's used (sparingly) for mechanical and aerospace structures. Sparingly, because accounting for strain hardening in non-linear materials like aluminum and stainless isn't easy even with FEA. If your material model is elastic-perfectly plastic it's a bit easier because the hunt for plastic hinges doesn't run into weird and wonderful material behaviors like plastic buckling or strain-softening or oddball effects of large displacements.
