Structural Dynamics (CIVL5268)


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. Outcomes: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
