Some Conclusions Some Conclusions
• Simplified Methods play a special role in Soil Dynamics. This role is different from, and cannot be replaced by, sophisticated computer simulations
• Understanding by engineer of basic Dynamics and Wave Propagation concepts increases usefulness of Simplified Methods
• Simplified Methods are available to calculate equivalent soil springs and dashpots under shallow embedded foundation of arbitrary shape
