Vibration Problems in Structures: Practical Guidelines
Birkhäuser, 1995
pdf, 237 pages, English
ISBN: 978-3764351489

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.

Sétra Technical guide - Footbridges Assessment of vibrational behaviour of footbridges under pedestrian loading
Sétra, 2006
pdf, 131 pages, English
ISBN: -

Description

These guidelines round up the state of current knowledge on dynamic behaviour of footbridges under pedestrian loading. An analytical methodology and recommendations are also proposed to guide the designer of a new footbridge when considering the resulting dynamic effects.

The methodology is based on the footbridge classification concept (as a function of traffic level) and on the required comfort level and relies on interpretation of results obtained from tests performed on the Solferino footbridge and on an experimental platform.

These guidelines are aimed at Owners, designers and engineers.

This document covers the following topics:

* a description of the dynamic phenomena specific to footbridges and identification of the parameters which have an impact on the dimensioning of such structures;

* a methodology for the dynamic analysis of footbridges based on a classification according to the traffic level;

* a presentation of the practical methods for calculation of natural frequencies and modes, as well as structural response to loading;

* recommendations for the drafting of design and construction documents.

Supplementary theoretical (reminder of structural dynamics, pedestrian load modelling) and practical (damping systems, examples of recent footbridges, typical calculations) data are also provided in the guideline appendices.
