Large structures such as factories, gymnasia, concert halls, bridges, towers, masts and chimneys can be detrimentally affected by vibrations. These vibrations can cause either serviceability problems, severely hampering the user's comfort, or safety problems. The aim of this book is to provide structural and civil engineers working in construction and environmental engineering with practical guidelines for counteracting vibration problems. Dynamic actions are considered from the following sources of vibration: - human body motions, - rotating, oscillating and impacting machines, - wind flow, - road traffic, railway traffic and construction work. The main section of the book presents tools that aid in decision-making and in deriving simple solutions to cases of frequently occurring "normal" vibration problems. Complexer problems and more advanced solutions are also considered. In all cases these guidelines should enable the engineer to decide on appropriate solutions expeditiously. The appendices of the book contain fundamentals essential to the main chapters.
Part 1 Vibrations induced by people: pedestrian bridges; floors with walking people; floors for sport or dance activities; floors with fixed seating and spectator galleries; high-diving platforms. Part 2 Machinery-induced vibrations: machine foundations and supports; bell towers; structure-borne sound; ground-transmitted vibrations. Part 3 Wind-induced vibrations: buildings; towers; chimneys and masts; guyed masts; pylons; suspension and cable-stayed bridges; cantilevered rooves. Part 4 Vibrations induced by traffic and construction activity: roads; railways; bridges; construction work. Appendices: basic vibration theory and its application to beams and plates; decibel scales; damping; tuned vibration absorbers; wave propagation; behaviour of concrete and steel under dynamic actions; dynamic forces from rhythmical human body motions; dynamic effects from wind; human response to vibrations; building response to vibrations.
