Non-linear identification of MDOF systems with hysteresis from seismic response data
A non-linear dynamic identification presupposes the availability of a huge quantity of experimental data,this being a requirement that is seldom satisfied in structural or earthquake engineering applications.The paper presents a technique for the identification of the hysteretic behavior of Multi-Degrees-of-Freedom(MDoF)systems subjected to seismic loading by defining proper instantaneous estimators of the dynamic properties:such estimators are defined by resorting to a Volterra series representation of a polynomial non-linear time-varying system whose dynamics is equivalent,to a certain extent,to the actual hysteretic behavior.A numerical application of the instantaneous identification of a 2DoFs hysteretic shear type frame under seismic excitation is presented.
