Dynamics of Marine Stationary Platform Under Action of Horizontal Seismic Loading
Abstract eng: Dynamics of a fixed sea-based offshore platform under action of the horizontal seismic loading is investigated. The structure consists of a tube-like ferroconcrete rod, of an upper platform, and of a pile foundation. To describe the structure motion the beam-like model is used. Some deterministic and random models of the seismic loading are proposed. The depth of water is of the order 250 meters, the attached mass of water and its resistance is taken into account, the surface waves influence on the motion is not studied. The system of partial differential equation is reduced to the system with 3 degrees of freedom. The main attention is paid to the piles deformations and to their strength. Some numerical examples are studied.
