Abstract. The article presents an analysis of published works on the state of regulatory documentation for the calculation of structures resistance to earthquakes; the author argues that the developers of domestic requirements made a serious methodological error setting the initial seismic information when they used dynamic coefficients, instead of response spectra; identified the reasons for the inadequacy of mathematical models of the interaction of foundations and structures during earthquakes, including for offshore oil and gas facilities, gives equations for translational, rocking parallel movements of a rigid structure on a pliable foundation, taking into account the effects of gravity. The author proposed to introduce these equations into the standards for earthquake-resistant construction and, on their basis, to analyze the stability of the structure's position.
