Appeals to the Student and the Seasoned ProfessionalWhile 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 systemsThe vibration of systems with multiple degrees of freedomThe vibration of continuous systems (strings, rods and beams)The essentials of finite-element vibration modellingSymmetry considerations and an outline of group and representation theoriesApplications of group theory to the vibration of linear mechanical systemsApplications of group theory to the vibration of structural grids and cable netsGroup-theoretic finite-element and finite-difference formulationsVibration Analysis and Structural Dynamics for Civil Engineers: Essentials and Group-Theoretic Formulations acquaints students with the fundamentals of vibration theory, informs experienced structural practitioners on simple and effective techniques for vibration modelling, and provides researchers with new directions for the development of computational vibration procedures.

Advances and Trends in Structural Engineering, Mechanics and Computation features over 300 papers classified into 21 sections, which were presented at the Fourth International Conference on Structural Engineering, Mechanics and Computation (SEMC 2010, Cape Town, South Africa, 6-8 September 2010). The SEMC conferences have been held every 3 years in Cape Town, and since then brought together academics, researchers and practitioners active in structural mechanics, associated computation and structural engineering. The main purpose of the conferences was to review recent achievements in the advancement of knowledge and understanding in these areas, share the latest developments, and address the challenges that the present and the future pose. All major aspects of structural mechanics, associated computation and structural engineering are addressed in the present volume, including: structural mechanics (dynamics, vibration, impact, buckling, seismic response, fluid-structure interaction, soil-structure interaction); mechanics of materials (plasticity, fracture, fatigue, creep, shrinkage, damage, deterioration); numerical/computational modelling (numerical methods, formulations, finite-element modelling, structural modelling, material modelling, simulations); structural engineering and construction in the various materials (steel, concrete, timber, masonry, glass, steel-concrete composite, fibre-reinforced composite, laminated composite); design, construction and operational considerations (fire resistance, seismic resistance, loading, safety and reliability, codification, design optimisation, construction, assembly, monitoring, maintenance, repair, retrofitting). The structures dealt with include all sorts of buildings, sports facilities, bridges, viaducts, tunnels, underground structures, foundation structures, coastal structures, dams, industrial towers and masts, containment structures (silos, tanks and pressure vessels), ship and aircraft structures, motor-vehicle structures, mechanical components and biological structures. Advances and Trends in Structural Engineering, Mechanics and Computation is published as a book of extended abstracts, and an accompanying CD-ROM with the full papers, and will be much of interest to engineers, academics and researchers in civil, structural, mechanical and aerospace engineering, and to those concerned with the analysis, design, construction and maintenance of engineering structures.

Shell Structures in Civil and Mechanical Engineering, joint winner of the University of Cape Town Book Award for 2019, comprehensively covers the theories governing the membrane and bending behaviour of thin elastic shells.
