Superelastic semi-active damping of a base-isolated structure

Application of semi-active control strategies for seismic protection of buildings with MR dampers

“…Furthermore, they are relatively inexpensive to manufacture and maintain and are insensitive to temperature so that they may be used for indoor and outdoor applications. Because of their mechanical simplicity, high dynamic range and low power requirements, they are considered as good candidates for reducing the structural vibrations and they have been studied by a number of researchers for seismic protection of civil structures [8][9][10][11][12].…”

Preliminary Experimental and Finite-Element Numerical Assessment of the Structural Performance of SMA-Reinforced GFRP Systems

“…the austenitic and the martensitic phases, respectively. Due to their intrinsic mechanical properties, SMAs have been largely used for Civil Engineering buildings and infrastructures in the form of active control systems in general (see Boroschek et al, 2007;Dolce and Cardone, 2005;Mc Cormick et al, 2006;Zhang and Zu, 2007;Shook et al, 2008;Wilde et al, 2000;Andrawes and Des Roches, 2007;Tamai et al, 2003;Savi et al, 2011, etc. ).…”

Numerical Simulation of a Semi-Active Vibration Control Device Based on Superelastic Shape Memory Alloy Wires

“…Most of these devices are built up of Nitinol (NiTi), a dual alloy built up of Nickel and Titanium (Zhang & Zu, 2007), due to its outstanding fatigue properties, high corrosion resistance and ductility. A hybrid base isolation system, composed of linear elastomeric bearings, friction-pendulum bearings, SE austenitic wires and magnetorheological dampers was proposed by Shook et al (Shook et al, 2008) for mitigation of seismic motions. To manage the superstructure response to ground motions, each subcomponent of the isolation system was designed for a specific task.…”
