Seismic protection of buildings and structures on the basis of

Of all the systems of seismic protection of buildings, the most common Seismic isolation, but many existing designs have a number of drawbacks, such as the complexity of manufacturing and installation, the inability to verify and replace the device, the unstable performance and low durability of such devices, so the purpose of this study is to create a simple, reliable, cost-effective shock absorber design for protecting buildings and Structures from seismic influences using a polyurethane elastomer. The tasks of this work are to study the mechanical properties of different brands Polyurethanes under different temperature conditions, dynamic and cyclic loads, to work constructively, that is, to improve existing shock absorber designs, to choose materials for elastic elements with the greatest energy intensity and to investigate the effect of temperature on the strength characteristics of polyurethanes
