Description
This article brings into consideration the possibility of intervention on an existing structure by adding secondary structural elements, equipped with viscous fluid dampers. The proposed goal is that the intervention is mini-mally invasive in terms of the use of the building during the execution. The herewith article analyses the ability of viscous fluid devices to fight against the effects of seismic actions, by increasing the fraction of critical damping. Adopting dampers can be an alternative to taking over structural damage, and can be seen as an alternate way to absorb the energy induced by the earthquake. The proposed intervention solution is based on reducing the seismic demand, in contrast to the classic consolidation solution, repre-sented by the increase in mechanical performance, a solution calibrated to the location in the specific seismic hazard in Romania.
