Purpose and Background
Structures (and equipment) are analyzed to identify their vulnerabilities to seismic ground shaking. The analysis is carried out by applying ground motions to a mathematical model of the structure. The ground motions are defined by their response spectra or time-histories. The structure is modeled by a lumped- or distributed-mass system. The nonlinearities are explicitly modeled or empirically considered. As a result, there are many different methods of analyzing a structure. The objectives of this seminar are to: (a) discuss the pros and cons of different methods of analysis; and (b) provide an understanding of the dynamic response of structures such that the most appropriate method of analysis can be selected and the most efficient design can be implemented.
Seminar Benefits
- To learn why seismic loads are different from other loads
- To gain a thorough understanding of the dynamic response of structures to seismic ground shaking
- To learn the benefits and limitations of 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
Assessment of Learning Outcomes
Learning outcomes will be assessed through discussions in the class.
