Considerations on functional parameters of dry friction seismic isolation systems

Résumé

Many types of isolation systems against ground seismic activities which can be attached to the building structures have experienced an intensive development in recent years. The studies and researches carried out on different experimental models aim to obtain continuous improvements for the isolation systems component parts so they can provide maximum efficiency in operation, and offer an improved behavior for structures to which are mounted during seismic events. This paper shows the working principle of isolation systems with dry friction depending on the main parameters involved and the linear force-displacement diagrams obtained from the case studies using different values of these design parameters.
