STOCHASTIC DYNAMIC RESPONSE ANALYSIS OF OFFSHORE PLATFORMS, WITH PARTICULAR REFERENCE TO GRAVITY-TYPE PLATFORMS

A computerized method for stochastic dynamic response analyses of framed structures with a Ciasson-type foundation has been developed. The dynamic response is determined by a finite element idealization of the structure. A lumped mass formulation is used. The effect of the soil is taken into account by a linear elastic half-space model, which provides equivalent spring- and dash-pot constants. Hysteretic damping in the soil is also included.
