Abstract
Influence of compressive force on the characteristics of a viscoelastic material
Incoming article date: 06.06.2022Currently, one of the most promising and cost-effective methods of seismic isolation is the use of passive energy dissipation systems. The research carried out in this article focuses on the use of a new hybrid energy dissipation device that combines a parallel layer of an inexpensive viscoelastic material and a metal component. Typically, the viscoelastic material in such systems is attached to steel shock absorbers with an adhesive. In this article, the behavior of a viscoelastic material is studied when it is attached to a metal component without the use of glue, being held only by friction and pressure. The influence of the compression force on the elastic and damping properties of a viscoelastic material arranged in a seismic damper has been established, and the pressing force has been determined, which ensures the optimal functional properties of the viscoelastic material.
