     performance level is served as an index defining the state of damage occurred in a building under specific ground motions, determining of which contains complex and iterative procedures that may not be straight-forward and accurate enough. this research aims to provide user-friendly and compatible tools in the form of a computer program in order to evaluate the performance level and seismic parameters of a structure, the capacity (pushover) curve data of which is obtained using any admissible method. the user-code is written in matlab programming and excel spread-sheet environments. it is capable of determining the performance point of the structure using atc-40 instructions, within a 0.5% tolerance. the exact bilinear representation of the capacity curve is also obtained, from which seismic parameters are extracted. the demand curves are automatically constructed by user-specified parameters according to the iranian seismic code (standard no.2800) for different seismic hazard levels and underlying soil types, as well as different ratios of structure’s effective damping.
