While the analysis of a civil-engineering structure typically seeks to quantify static effects (stresses and strains), there are some aspects that require considerations of vibration and dynamic behavior. Vibration Analysis and Structural Dynamics for Civil Engineers: Essentials and Group-Theoretic Formulations is relevant to instances that involve significant time-varying effects, including impact and sudden movement. It explains the basic theory to undergraduate and graduate students taking courses on vibration and dynamics, and also presents an original approach for the vibration analysis of symmetric systems, for both researchers and practicing engineers. Divided into two parts, it first covers the fundamentals of the vibration of engineering systems, and later addresses how symmetry affects vibration behavior.
Part I treats the modeling of discrete single and multi-degree-of-freedom systems, as well as mathematical formulations for continuous systems, both analytical and numerical. It also features some worked examples and tutorial problems. Part II introduces the mathematical concepts of group theory and symmetry groups, and applies these to the vibration of a diverse range of problems in structural mechanics. It reveals the computational benefits of the group-theoretic approach, and sheds new insights on complex vibration phenomena.
The book consists of 11 chapters with topics that include:
The vibration of discrete systems or lumped parameter models
The free and forced response of single degree-of-freedom systems
The vibration of systems with multiple degrees of freedom
The vibration of continuous systems (strings, rods and beams)
The essentials of finite-element vibration modelling
Symmetry considerations and an outline of group and representation theories
Applications of group theory to the vibration of linear mechanical systems
Applications of group theory to the vibration of structural grids and cable nets
Group-theoretic finite-element and finite-difference formulations
