hi abouferass88
as we knew there are 2 main purposes of performance-based seismic engineering for building namely seismic design & seismic evaluation. the first needs the lateral force based on design spectrum for pushover analysis so that the capacity and demand spectrum can be generated, whereas the second may be capacity evaluation only, which means we could push the building till instability occurs, regardless what design spectrum governed.
