This toolbox is suitable for carrying Dynamic Response Spectrum Analysis (DRSA) for a given structure, as well as producing linear elastic response spectra and elastoplastic response spectra, using elastic-ideally plastic force-deformation relation. The necessary functions included involve apart from DRSA and spectra production, linear interpolation, eigenmode combination rules, refinement of time history in case the time step needs to be reduced, etc.
