Nowadays, performance-based designing method has been introduced as an alternative to seismic designing of buildings due to increasing construction of high buildings and available inadequacies in related codes. The concept of performance-based designing is described as achieving one or more functional objectives indicating to a performance level on a specific seismic level. Therefore, some structures have been designed as moment-resistance frames according to 2800 code of Iran and steel codes. Nonlinear model of structure with definite specification have been created based on structural specifications and profiles designed in this stage. The nonlinear time history has been analyzed using earthquake records scaled to designing spectrum. Finally, the performance level of structure has been discussed comparing the quantities related to performance levels such as the relative displacements of the stories, plastic joint rotations, etc. considering the code limitations of every performance level.
