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 [...]

Undesirable seismic performance or failure of non-structural components (NSCs) during earthquakes is reported as a major portion of seismic economic loss. To prevent or r [...]

This paper describes analytical and experimental studies into the effectiveness and feasibility of semi-active resettable devices for seismic protection of civil engineer [...]

The seismic performances of multi-story passive and semi-active tuned mass damper (TMD) building systems are investigated for 12-story moment resisting frames modeled as [...]

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 [...]
