    Slender structures exposed to a strong vertical component of an earthquake excitation are endangered by auto-parametric resonance effect. If an amplitude of a vertical harmonic excitation in a structure foundation exceeds a certain limit, vertical response at the top ot the structure looses its stability and a dominant horizontal response component arises. Qualitatively different post-critical response types have been detected when sweeping throughout the frequency interval beyond the stability limit. Deterministic as well as chaotic response types have been observed. In general they can occur in a steady state, quasi-periodic and completely undetermined regimes including a possible energy transflux among degrees of freedom.
