“…Following them, Deng et al (2003Deng et al ( , 2006 studied the effect of different properties, such as initial prestrain of SMA wires, modes of activating electrical current, and the actuation times, on the behavior of prestressed beam. Recently, El-Tawil and Ortega-Rosales (2004) and Sawaguchi et al (2006) examined different experimental aspects of the post tensioning procedure. Finally, in case of thin walled members, and for small tension stresses, the use of SMA bars is not feasible anymore; for this purpose, SMA fibers may be embedded in the cement matrix, as suggested by Moser et al (2006).…”
