Structural Dynamics (CIVL5268)
UNIT OF STUDY
This Unit introduces the fundamental concepts and theory of dynamic analysis. In a first step, free vibrations are studied and the problem of determining the natural frequency of a system is addressed. This is followed by the study of harmonically excited vibrations. While initially systems with a single degree of freedom (SDOF) are considered, the theory is generalized to cover multi-degree of freedom systems. The theory is applied to explain how structures are designed against earthquake actions with specific reference to Parts 4 of the Australian loading standard AS1170 for determining earthquake loads.
This Unit will provide students with the following knowledge and skills:
* Understanding of the fundamental concepts and definitions used in structural dynamics
* Ability to calculate the natural frequency of a system using equilibrium or energy methods
* Ability to determine the effect of viscous damping on the response of a freely vibrating system
* Ability to determine the response of a system to a harmonic excitation
* Ability to apply AS1170 Part 4 in structural design against earthquake actions
* Understanding of the fundamental concepts of earthquake engineering

Study this unit outside a degree
If you wish to undertake one or more units of study (subjects) for your own interest but not towards a degree, you may enrol in single units as a non-award student.
If you are from another Australian tertiary institution you may be permitted to underake cross-institutional study in one or more units of study at the University of Sydney.
