Advanced Structural Dynamics
This course focuses on modal analysis that is a fundamental technique for investigating dynamic characteristics of structures.
The purpose of this class is to provide a presentation for the theory of modal analysis.
- To understand multiple-degree-of-freedom systems
- To understand theoretical modal analysis
- To analyze time history response of multiple-degree-of-freedom systems based on modal analysis

Relationship between 'Goals and Objectives' and 'Course Outcomes'
Evaluation method and criteria
The score will be counted from 100 point by report. The pass criteria is 60 point. The threshold of 60 point is to obtain
a frequency response function and mode shapes of a three-degree-of-freedom system.
