Tuned inerter dampers with linear hysteretic damping [PDF]
Earthquake Engineering and Structural Dynamics, 2020 This paper explores the influence of linear hysteretic damping on the performance of passive tunedinerter devices. An inerter is a device that produces a force proportional to the relative acceleration across its two terminals; devices incorporating ...

Causality in real-time dynamic substructure testing [PDF]
, 2009 Causality, in the bond graph sense, is shown to provide a conceptual framework for the design of real-time dynamic substructure testing experiments. In particular, known stability problems with split-inertia substructured systems are reinterpreted as ...

Experimental calculation of the damping ratio in buildings hosting permanent GPS stations during the recent Italian earthquakes [PDF]
, 2018 During the recent earthquakes in Italy, the contemporary presence of about 40 permanent GPS and 40 accelerometric stations of the national seismic network made it possible to estimate the value of the damping ratio of the buildings hosting the GPS ...

Identification of the extended standard linear solid material model by means of experimental dynamical measurements [PDF]
, 2023 A novel algebraic procedure for the non-parametric identification of the material model by means of dynamical test measurements is proposed. An extended Standard Linear Solid (SLS) material model is taken into account to model the material linear visco ...
