The frictional Ring-spring (RS) is a dissipative spring that is used to provide restoring forces and dissipation in a single device. It thus offers significant re-centrin [...]

Many current active and semi-active supplemental damping devices are highly complex, limiting robustness, and those that can generate larger response forces typically suf [...]

This paper describes the development of a numerical model to predict the behaviour of a semi-active resettable tendon during seismic testing. Two resettable tendons were [...]

A main goal of supplemental control devices is to manage the energy dissipation in the system. Magneto-rheological (MR) dampers have emerged as a promising control device [...]
