Nonlinear response analysis considering dynamic stiffness with both frequency and strain dependencies / Naohiro Nakamura in Journal of engineering mechanics, Vol. 134 N° 7 (Juillet 2008) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 134 N° 7 (Juillet 2008) . - pp.530-541 Titre : Nonlinear response analysis considering dynamic stiffness with both frequency and strain dependencies Type de document : texte imprimé Auteurs : Naohiro Nakamura, Auteur Année de publication : 2010 Article en page(s) : pp.530-541 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Stiffness  Nonlinear  response  Strain  Earthquakes. Résumé : The time domain evaluation of the frequency-dependent dynamic stiffness was studied and some transform methods are being proposed. In this paper, the nonlinear response analysis method of the dynamic stiffness with both frequency and strain dependency was studied. First, the frequency-dependent complex stiffness was calculated at each strain level, and then they were transformed to the impulse response in the time domain. The characteristics of the complex stiffness and the impulse response of both two-layered soil and viscoelastic dampers were investigated. Then, the nonlinear time-history response analysis method considering both dependencies using the impulse response of each strain level was proposed. The earthquake response analysis of a structure on the two-layered soil was carried out as an example. The efficiency of the method was confirmed through these investigations.
