Book Description
Damage to structures due to vibrations from pile driving operations is of great concern to engineers. This research has stemmed from the need to address potential damage to concrete-filled pipe piles and recently placed concrete structures that could be affected by pile driving vibrations. The study will focus on two topics: (1) The attenuation of potentially damaging pile driving vibrations with distance from the source, and (2) The effects of distance and curing time of concrete on the quality (unconfined compressive strength) of recentlyplaced concrete exposed to pile driving vibrations. The effects of pile driving vibrations did not cause problems with concrete compressive strength except for the case where concrete had only cured for 4 to 6 hours before vibration.

Book Description
A composite concrete floor is proposed in this book to suppress stationary random vibration in concrete structures using a compound vibration absorber named vibration damping compound (VDC). While the traditional vibration absorber can damp down the vibration mainly at the pre-tuned mode of the primary structure, active damping is generated by the proposed VDC to damp down all resonant modes of interest of the vibrating structure and the spatial average mean square motion of the vibrating structure can be minimized. Only one absorber and one feedback signal are required to achieve vibration suppression of a concrete structure under stationary random excitation. A special composite concrete floor is designed such that all vibration modes of the concrete structures become critically damped. It is proved analytically that the proposed VDC damps the vibration of the entire structure instead of just the attachment point of absorber.

Book Description
Authors: Hugo Bachmann, Walter J. Ammann, Florian Deischl, Josef Eisenmann, Ingomar Floegl, Gerhard H. Hirsch, Günter K. Klein, Göran 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.
