Based on these theories, methods for construction of design earthquake ground motions are presented. Soil-structure interaction problems are stated finally for the purpose of developing more rational design methods for building structures. Course Goals Obtain the knowledge on wave propagation theories and 1D multi-reflection theory of waves.
