Abstract

[en] The effectiveness of Tuned Liquid Dampers (TLD) on a bridge deck in the lifting
phase against flutter instability is presented. The following study represents an
experimental investigation. A linear analytical approach was used for predimensioning
the TLD. Based on that, TLDs were built and tested on a shaking table. The
experimental results were not in good agreement with the analytical method therefore
new tanks were constructed in order to conduct the experiment in the wind tunnel. A
scaled model of the deck of Bosphorus Bridge is analyzed as an illustrative example.
The effectiveness of the TLD system in increasing the critical flutter speed of the deck
is investigated through a parametric study, which led to the optimization of
paramaters such as height of water or position of the water tanks which provide
maximum critical wind speed for the deck section. The result of the experiment shows
that the critical flutter velocity is increased compared to the deck alone, but the
tuning condition is not obtained since the tanks filled with water exhibit an in-phase
motion with the deck. This study may open a broad range of questions regarding the
utilisation of unconventional techniques for this particular problem and different
solutions may be tested and adopted given the variety of available techniques.
