Efficiency of viscoelastic interstructural connections to prevent earthquake induced pounding
This work deals with the efficacy of viscoelastic connections in preventing pounding without undesirable adverse effects on the coupled structures. To this end, the earthquake response of two oscillators, coupled with optimally designed passive viscoelastic and active devices as well as with rigid connections, was studied. A particular attention was given to two issues: (a) the upper limit of the device force and (b) the capacity of the device in reducing the interstructures displacement to avoid collision. The main conclusion of the paper is that, in general, there is no substantial benefit from the use of viscoelastic connections as a means to prevent pounding.
