Ammann, Florian Deischl, Josef Eisenmann, Ingomar Floegl, Gerhard H. Hirsch, Gu?nter K. Klein, Go?ran J. Lande, Oskar Mahrenholtz, Hans G. Natke, Hans Nussbaumer, Anthony J. Pretlove, Johann H. Rainer, Ernst-Ulrich Saemann, Lorenz Steinbeisser. 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. 606 $aMultibody systems 606 $aVibration 606 $aMechanics, Applied 606 $aEngineering 606 $aBuildings$xDesign and construction 606 $aMultibody Systems and Mechanical Vibrations 606 $aTechnology and Engineering 606 $aBuilding Construction and Design 615 0$aMultibody systems. 615 0$aVibration. 615 0$aMechanics, Applied. 615 0$aEngineering. 615 0$aBuildings$xDesign and construction. 615 14$aMultibody Systems and Mechanical Vibrations. 615 24$aTechnology and Engineering. 615 24$aBuilding Construction and Design. 676 $a620 700 $aBachmann$b Hugo$4aut$4http://id.loc.gov/vocabulary/relators/aut$0746000 702 $aAmmann$b Walter J.$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aDeischl$b Florian$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aEisenmann$b Josef$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aFloegl$b Ingomar$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aHirsch$b Gerhard H$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aKlein$b Günter K$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aLande$b Göran J$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aMahrenholtz$b Oskar$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aNatke$b H.
