## Course Title : Building Geoenvironment Engineering

Code 10B226 Master Course 2nd term Tue 1st C1-192 2 No Restriction Lecture Japanese I.Takewaki

### Course Description

Wave propagation theories are explained first for 1D, 2D and 3D models. 1D multi-reflection problems of waves are also formulated and explained. 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.

Evaluated by the term examination at the end of the semester.

### Course Goals

Obtain the knowledge on wave propagation theories and 1D multi-reflection theory of waves. Furthermore obtain the knowledge on construction of design earthquake ground motions and soil-structure interaction.
