Kharlanov V. L.

Insulators of pendular type are used widely for seismic isolation of structures with rigid constructive scheme. Existing calculation methods are based on the proposition of linear connection between restoring force and movement that isn’t always justified. The author offers the calculation method for nonlinear system based on mathematical pendular model. The spectrum of reactions of seismic isolated linear oscillators is calculated.
