Three-dimensional finite element model was established in ANSYS. To verify the model behavior the calculations with the displacement of the mass point were performed and comp а red with experimental one. The dissipated energy and damping coefficient for each half-period of oscillations were determined from the simulation results. The FEM modeling results show that the damping device can handle a mass of 6 tones under the dynamic loading. © 2024 The Authors . Published by ELSEVIER B.V.

Introduction The application of shape memory alloys (SMAs) in building structures has been a relevant topic over the past decade. Research interests encompass a broad spectrum of elements, such as self-centering connections, braces, dampers, and reinforcement bars for reinforced concrete structures. Damping systems are crucial in safeguarding industrial and civil infrastructure during earthquakes by energy dissipation (Iasnii et al., 2023). Active, semi-active, and passive devices and control systems are used to prevent or minimize the destructive consequences of earthquakes (Silva et al., 2015; Wang et al., 2020). Most of these systems rely on functional materials, particularly VII International Conference “In -service Damage of Materials: Diagnostics and Prediction ” (DMDP 2023) Modelling of the functional properties of the SMA-based damper device V.
