Pendulum isolators are widely used for seismic isolation of structures with rigid framing schemes. The existing design methods are based on the assumption of a linear relationship between the restoring force and displacement, this being justified for small displacements. The paper proposes the method for the nonlinear system analysis based on a simple pendulum model. The response spectra of seismo-isolated linear oscillators for actual accelerograms are calculated.
