Numerical analysis of a new SMA-based seismic damper system and material characterization of two commercial NiTi-alloys

J. S. Olsen, C. Van der Eijk and Z. L. Zhang

Abstract

The work presented in this paper includes material characterisation and an investigation of suitability in seismic dampers for two commercially available NiTi-alloys, along with a numerical analysis of a new damper system employing composite NiTi-wires. Numerical simulations of the new damper system are conducted, using Brinson
