In this article reaction of multistory concrete building with seismic protection systems in the form of friction pendulum bearings to the earthquake is researched. Seismic isolation bearings of the company FIP Industriale were chosen for seismic isolation of building. Researches are carried out using the software package LS-DYNA. Analysis of work of 16‑storey concrete building at seismic load, given as a two-component accelerograms normalized to 9 points on the MSK‑64 scale, is carried out. The calculations are carried out by the direct dynamic method. The main results include numerical values of upper isolator displacements relative to its bottom at different variants of the dominant frequencies of external influence. Bearing failure criterions depending on the parameters of seismic load are presented in the conclusions.
