The factors to affect the dynamic response of pipeline, including seismic wave types and input directions are studied in the dynamic experiments. A hydrodynamic force model on the base of Wake force model is presented to analyze dynamic response of free spanning submarine pipeline under earthquakes. Using finite element method, discrete equations of motion are derived from the hydrodynamic force model. Three dimensional FE model is established to simulate the experimental conditions. The numerical results considering sine wave inputs and simulated El centro earthquake inputs are obtained. The comparison of numerical results with experimental results shows that the improved Wake force model could satisfactorily predict dynamic response on the free spanning submarine pipelines subjected to earthquakes.
