Inelastic design spectra based on the actual dissipative capacity of the hysteretic response
AbstractThis work is intended at generalising the μd-T-Rμ relationships, currently available in the literature for defining inelastic design spectra, with the aim to take into account the actual dissipative capacity of structural systems. In fact, the inelastic spectra currently adopted in Nonlinear Static Analyses are generally based on an ideal elastic-perfectly plastic behaviour. Therefore, a more general hysteretic law is considered for parameterising the dissipative capacity of the structural systems under consideration. Non Linear Time History analyses are carried out for evaluating their dynamic response. A calibration of the aforementioned μd-T-Rμ relationships is proposed for enhancing the accuracy of inelastic seismic design spectra and, hence, the resulting relationships widely adopted in seismic analysis procedures, such as the N2 Method.
HighlightsInelastic Response Design Spectra are often based on elastic-perfectly plastic systems.Structures generally exhibit less dissipative cyclic response than such ideal systems.IRDS should take into account the actual dissipative capacity of structures.A simplified system is considered herein for parameterising the dissipative capacity.Simple rules for extending the current definition of IRDS are proposed.
