Shear link devices are metallic dampers that can be adopted to control structural vibrations induced by seismic and wind loads due to their typical rate-independent hysteretic behavior. To allow for an accurate and computationally efficient nonlinear dynamic analysis of structures equipped with shear links, we briefly present both the analytical and differential formulations of the Vaiana-Rosati model of hysteresis. Such a phenomenological model has been recently implemented in NextFEM Designer, a computer program for finite element analysis. To simplify the hysteresis model calibration, some preliminary details on a parameter identification procedure are provided. Finally, nonlinear time history analyses are carried out, by using NextFEM Designer, on a structure subjected to earthquake excitation.
