N2 - Advanced investigation on resonance phenomenon leads to the enhanced seismic design methodology. One proper seismic approach, which has been established based on the structural resonance influence, is the critical excitation method. Regarding to the combination of the random vibrations theory, the critical excitation methods, and some mathematical efforts, this paper is designed to propose a newtechnique for estimating the effects of the resonance phenomenon on the structural behavior. It is then introduced a new relationship between the probability of the structural resonance and the structural responses in the frequency domain. Therefore, by using the proposed method, the essential information of the structural frequency's content and Power Spectra Density (PSD) of the earthquake will be illustrated; following, the capacity of structural resonance would be estimated. Furthermore, by considering the safety target level of the seismic performance of the structures, it is possible to improve the structural resonance capacity of the existing structure.
