description	The main sources of the uncertainty in estimation of structural seismic responses is the uncertainty of the earthquake records as the input excitations. In recent years, along with the development of performance-based seismic design approaches, importance of the record selection strategies in nonlinear response history analysis of structures has been highlighted and has attracted the attention of many researchers. Record selection in performance-based seismic design approaches is often done based on the intensity measure of the records. The spectral shape has been introduced as a powerful intensity measure in record selection techniques for estimation of some structural responses such as the maximum inter-story drift ratio. In the present study, the sufficiency of the spectral shape in assessment of hysteresis energy of the structure and the maximum Park Ang damage index in plastic hinges has been investigated in special moment-resisting RC frames. In this way, four 2D structural models of special moment-resisting RC frames with inelastic characteristics have been analyzed under a set of strong ground motion records selected based on the spectral shape by the conditional spectrum method.
