Flutter Vulnerability Assessment of Flexible Bridges
This book is a revised and extended version of the author\'s
doctoral dissertation written in the framework of the International
Doctoral Course on \"Risk Management in the Built
Environment\", jointly held by the University of Florence,
Italy and TU Braunschweig, Germany. Modern bridges are sensitive to
wind loads and aeroelastic phenomena due to the tendency to design
always lighter and more flexible structures. Flutter instability is
a particularly concerning issue as it can provoke the collapse of
the bridge. In this work aerodynamic derivatives are considered as
random variables and flutter is probabilistically approached via
Monte-Carlo simulation. For this purpose a bridge deck model was
experimentally studied in the CRIACIV wind tunnel. Moreover, the
flutter problem is analytically investigated in order to enhance
existing codes and standards. In particular, an approximate formula
retaining only three aerodynamic coefficients is derived and
validated by means of a large number of experimental data. This
book is addressed to scientists and researchers dealing with wind
engineering, bluff-body aerodynamics and bridge aeroelasticity, as
well as to professional bridge engineers.
