• To gain a thorough understanding of the dynamic response of structures to seismic ground shaking.
• To learn about different methods of seismic analysis.

Learning Objectives

·         What characteristics of seismic ground motions affect the response of structures?

·         What are the dynamic characteristics of a structure?

·         Why it is important to know both forces and deformations experienced by a structure.

·         When it is more effective to design a stiff structure and when it is more effective to design a flexible structure.

·         How can a structure be analyzed without the use of empirical factors?

·         What characteristics of a structure are most effective in improving its seismic performance?

·         What are the appropriate methods of analysis in performance-based seismic design?
