Course description and aims
In this course, students first learn about seismic damage, the impetus for seismic design, and gain an understanding of damage mechanisms. After understanding damage mechanisms, students will gain an understanding of the components of design input seismic motions, seismic calculation models, and reference methods, which are the basic elements of seismic designs, as well the essentials of practical design.
The next step is to get a picture of the differences between and respective advantages of specification design methods and performance design methods, which are the major design systems. Students will also learn that performance design methods are more rational.
The final step is to gain an understanding of nonlinearity and the fracture properties of structure-supporting foundations during an earthquake. Students will learn to understand that performance design requires advanced analysis that portrays these properties, and specific examples of analysis methods. Students will learn the ability to choose the optimal analysis method.
Student learning outcomes
By the end of this course, each student will be able to:
1. describe the mechanisms of seismic damage.
2. choose from two levels of design input seismic motion that can be applied in practice.
3. Select analysis method that takes into consideration nonlinearity of foundations and concrete, and create nonlinear parameters for each.
4. Evaluate safety based on structure's sectional force and residual deformation obtained by seismic calculations.
Keywords
earthquake disaster, design input ground motion, performance based design, nonlinear seismic response analysis, seismic resistance improving technology
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
In each lecture, specific examples of handling problems are shown, and the instructor explains in particular the parts which are not written in the design standards. By showing topics that an aspiring engineer should be able to handle, students are constantly reminded to perform safe and rational seismic design.
