The study of seismic resistance of rubber-metal supports

This research reveals the efficiency of seismic isolation system in the form of rubber-metal supports with different height buildings at multi component seismic impact. As an example, seismically insulated monolithic reinforced concrete 5, 9 and 16 story buildings are considered. The solution of the problem is obtained by a direct integration of the motion equations for an explicit scheme in finite element formulation developed in the software package LS-DYNA. The calculation is performed considering nonlinear nature of rubbermetal supports. The analysis of the effectiveness of buildings with seismic insulation and without it is performed and the obtained results are presented.
