A mathematical model is developed to determine the response of permanent offshore structures which are embedded in the ocean floor and which are subject to harmonic or random waves. The usual assumption of a rigid foundation is not made, but the resistance of the soil to structural movements is included in the model. The type of structures for which this model is applicable are, in general, space-frames. This type of structure has been used in offshore petroleum installations. However, it is noted that the model is equally valid for a space-frame on land subject to dynamic forces or seismic disturbances.
