Structural Dynamics in Civil Engineering

Course title

H0936000

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
