ABSTRACT
A comprehensive settlement on the seismic impact of the gravitational platform, which in two settlement schemes consistently takes into account the vertical and horizontal impact on her. The first (quasi-static) takes into account the vertical oscillations of buildings, taking into account the added mass on the assumption that the construction zone near the epicenter. In this foundation is regarded as a beam lying on the ground, a variable stiffness of the foundation soil in view of plastic deformation. The second design scheme allows for horizontal seismic effects in the assumption that the epicenter is removed from the structure. To account for the seismic load from vibrations Colon dynamic spectral method is used as an expansion of the resulting seismic vibrations in a row on the main forms of oscillations. The results of calculation of the elements of the gravitational drilling platform in two settlement schemes using the program SCAD.
