Study of Lead Rubber Bearings Operation with Varying Height Buildings at Earthquake☆

The paper studies the efficiency of seismic isolation system in the form of lead rubber bearings with different height buildings at multicomponent seismic impact. As an example, seismically isolated monolithic ferro-concrete 5-, 9- and 16-storey buildings are considered. The solution of the problem is obtained by a direct integration of the motion equations for an explicit scheme in the software package LS-DYNA. The calculation is performed considering the nonlinear nature of lead rubber bearings. The analysis of the effectiveness of buildings with and without seismic isolation it is performed.
