| Outline and Purpose of the Course | This course provides the knowledge of simulation methods for earthquake engineering. Small groups of students are exercised in the prediction of ground motion generated by a specified seismic fault and the response analysis of structure selected by themselves considering soil-structure interaction. | |||
| Course Goals | At the end of this course, students will be required to have a good understanding of: - Prediction of ground motion generated by a specified seismic fault - Dynamic response analysis of structures and foundation (linear/nonlinear) | |||
| Schedule and Contents |
1. Frequency domain analysis Basics of Fourier transformation is introduced. 2. Modeling of structure - soil system and time domain analysis Equation of motion of SR model is introduced and the integration method of the equation in time domain is explained. 3-4. Exercise of linear seismic response analysis Small groups of students are exercised in elastic modeling of structures and linear response analysis in time domain and frequency domain. 5-7. Prediction of ground motion by empirical Green's function method Empirical Green's function method is introduced to predict large earthquakes based on observed small earthquakes. 8-9. Seismic analysis method of soil Seismic analysis method of layered half-space based on equivalent linearization method is introduced. 10-11. Nonlinear seismic analysis method of structures Nonlinear modeling of structures and the integration and iterative methods of the nonlinear equation of motion in time domain are introduced. 12-14. Exercise of nonlinear seismic response analysis Small groups of students are exercised in the prediction of ground motion generated by a specified seismic fault and the nonlinear response analysis of structures and foundation. 15. Achievement Check All students give presentations and discussions. |
