Course title
Structural Dynamics in Civil Engineering

KONNO Katsuaki
Course description
In this class, the structural dynamics problem is formulated for simple elastic structures, which can be idealized as single-degree-of-freedom (SDF) Systems, and some methods for solving the differential equation governing the motion of the structure are reviewed. We then study the dynamics response of linearly elastic systems in free vibration, to harmonic and periodic excitation. After presenting a numerical time-stepping method for calculating the dynamic response of SDF Systems, the earthquake response of linearly elastic systems is studied, and response spectra are presented.
Purpose of class
The purpose of class is to understanding dynamic characteristics of structures.
Goals and objectives
  1. Understand SDOF systems
  2. Understand the dynamic response of structures
  3. Understand the response spectrum
