Summary: Seismic vulnerability of buildings and infrastructural assets is a significant source of concern globally. Poorly designed and constructed structures can result in severe structural and non-structural damage even under moderate earthquakes, while local and global collapses can occur in case of high-intensity events. Various retrofitting strategies have been developed over the years to mitigate the resulting risk. These interventions aim to increase the capacity of seismically deficient structures and/or reduce the seismic demand by changing their dynamic behaviour. The use of tuned mass dampers (TMD), base isolation systems (BIS) and energy dissipation devices (EDD) belongs to the latter category. While adopting these technologies is relatively straightforward for new constructions, their implementation in existing buildings, particularly those with heritage value, is fraught with difficulties.

This special session of SEMC 2022 aims to provide a forum for the exchange of information between researchers and professional engineers working on theoretical developments and practical applications of inertia-based devices and other forms of passive control of earthquake-induced vibrations. Topics include (but are not limited to) mass dampers, inerters, viscoelastic and viscous-fluid dampers, elastoplastic dampers, elastomeric and friction isolators. Of particular interest are contributions presenting new advances and case studies in which multiple mechanisms of vibration control have been synergistically adopted and/or special design constraints have resulted in the implementation of unusual control solutions.
