Summary:

The course is organized into four parts: I. Basic Seismology; II. Dynamics of Structures; III. Earthquake Resistance Building Structures; and IV. Earthquake Resistance Bridge Structures.

To study earthquake engineering, an understanding of how the earthquakes occur and their effects on ground motion is required. Advances in seismology have produced a good understanding of the mechanisms and rates of occurrence of earthquakes. Part I provides a brief introduction to this subject. In Part II the structural dynamics problem is formulated for simple elastic and inelastic structures, which can be idealized as single-degree-of-freedom (SDF) or multi-degree-of-freedom (MDF) systems. Coverage of these topics should help the students to apply structural dynamics theory in practical problems, especially in earthquake analysis and design of structures. Part III contains the subjects concerned with earthquake response and design of multistory buildings. Building codes are also presented and discussed with their relationships to the theory of structural dynamics. Part IV is similar to Part III, except Part IV deals with bridges instead of buildings.

The information presented in this course should be of special value to those students who either are engaged in or interested in actual seismic design and want to improve their understanding of the subject.

Course Workload:

Readings (textbook, selected journal papers, additional handouts)
4 Homework assignments (textbook problems, MathCad, spreadsheets, WorldWide Web exploration)
One midterm (after spring break)
One project
Final exam (schedule and format to be determined)
