PARAMETRIC CORRELATIONS BETWEEN THE ELASTOMER PHYSICAL AND MECHANICAL PROPERTIES AND THE SEISMIC 2 ELASTOMERIC ISOLATORS PERFORMANCES

Abstract

The paper presents the parametric correlations between the elastomer physical and mechanical properties(equivalent elasticity module, tensile strength, compressive deformation degree, etc.) the constructive solution of elastomeric seismic isolators(geometric and dimensional characteristics),and the performance parameters which determine the capacity for use of these devices, within different solutions for the seismic protection of bridges subjected to low seismic actions. The aim is to identify and quantify the factors that influence, in a decisive way, the elastomeric seismic performances isolators, so that an analysis method to be established , which allows the evaluation by calculation, with an appropriate degree of accuracy, of the behaviour and the performance characteristics for different constructive types of such products.
