1. Object
This course provides students with the basic theories on the dynamic behavior of infrastructures subjected to earthquake ground motions and the seismic design methods.
2. Outline
In this course, students learn the dynamic behavior of structural members such as concrete members, dynamic response analysis of structures, and basic characteristics of earthquake ground motions.
