In this article modeling of the system active seismic protection (seismic isolation) of buildings in the form of friction pendulum bearing is made, which has some use in Earthquake Engineering abroad, but not enough researched now. Friction pendulum bearings of the company FIP Industriale are considered. Numerical researches of the work of seismic isolation are carried out at periodic lateral load with different parameters of external influence. The main results include numerical values of displacements of the friction pendulum bearing and shear forces, force-displacement relation of seismic isolation, at the external periodic load. Conclusions reflecting the criteria for the selection of a friction pendulum bearing depending on the parameters of external influence are formulated. Researches are carried out using the software package LS-DYNA.
