摘要：
The hysteresis exhibited by short steel wire ropes is shown to lend itself as an effective restoring force for nonlinear monodirectional tuned mass dampers. Experiment-driven modeling based on the identified hysteretic restoring forces together with continuation tools enables an optimal design of these dampers through construction of families of frequency-response curves over a wide range of excitation amplitudes. Semi-analytical/ numerical and experimental studies are carried out considering a base-excited test structure represented by a simply supported beam together with a prototype of the hysteretic damper subject to either harmonic or filtered Gaussian white noise excitations.
