Abstract
The paper studies the influence of a shape memory alloy (SMA) element on the dynamic response of a single-degree-of-freedom- system, representing a structural building under earthquake excitation. Variations of the SMA geometry are studied by numerical simulation, and a value for the SMA radius is determined, which provides optimal system performance. In particular do we focus on the role of hysteresis-induced passive damping, which can potentially be exploited for the development of SMA-based semi-active control schemes.
