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 rubber-metal supports. the analysis of the effectiveness of buildings with seismic insulation and without it is performed and the obtained results are presented.
