Simplified method to include cumulative damage in the seismic response of single-degree-of-freedom systems / Cosenza, Edoardo in Journal of engineering mechanics, Vol. 135 N° 10 (Octobre 2009)  

Public ISBD [article]  inJournal of engineering mechanics > Vol. 135 N° 10 (Octobre 2009) . - pp. 1081-1088 Titre : Simplified method to include cumulative damage in the seismic response of single-degree-of-freedom systems Type de document : texte imprimé Auteurs : Cosenza, Edoardo, Auteur ; Manfredi, Gaetano, Auteur ; Polese, Maria, Auteur Article en page(s) : pp. 1081-1088 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Ductility Fatigue Damage Seismic effects. Résumé : In this paper a consistent method including damage criteria in the seismic response of single-degree-of-freedom systems is proposed. The method allows the determination of suitably modified strength or displacement inelastic spectra through the introduction of an equivalent damage factor pdam that accounts for earthquake damage potential; analogously capacity spectra could be obtained. Three types of damage indices are considered (Park and Ang index DP&A, energy index DE, and low-cycle fatigue index DF) and derivation of pdam is pursued for all these cases. Moreover approximate simplified expressions in the function of Cosenza and Manfredi seismological ID index, which accounts for cyclic damage potential of an earthquake, are also proposed. In this way damage capacity spectra are obtained to improve the seismic assessment of existing structures including damage effect.
