This lecture covers the course objectives related to seismic design of structures, including seismic engineering principles, design considerations for dynamic ground motion, shake table tests, and failure modes during earthquakes. It emphasizes the importance of deformation capacity in earthquake performance and the tasks of engineers in designing new and retrofitting existing buildings. The content also includes an overview of seismicity, damage patterns, design methods, and evaluation of structures. The course structure, assignments, quizzes, and exam details are outlined, along with contact information for teaching assistants. Various topics such as inelastic behavior of RC walls, capacity design, and displacement-based assessment are discussed.
