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.

A topic of utmost importance in civil engineering is finding optimal solutions throughout the life cycle of buildings and infrastructural objects, including their design, manufacturing, use, and maintenance. Operational research, management science, and optimization methods provide a consistent and applicable groundwork for engineering decision-making. These topics have received the interest of researchers and, after a rigorous peer-review process, eight papers have been published in this Special Issue. The articles in this Printed Edition demonstrate how solutions in civil engineering, which bring economic, social, and environmental benefits, are obtained through a variety of methodologies and tools. Usually, decision-makers need to take into account not just a single criterion, but several different criteria and, therefore, multi-criteria decision-making (MCDM) approaches have been suggested for application in five of the published papers; the rest of the papers apply other research methods. Most approaches suggested decision models under uncertainty, proposing hybrid MCDM methods in combination with fuzzy or rough set theory, as well as D-numbers. The application areas of the proposed MCDM techniques mainly cover production/manufacturing engineering, logistics and transportation, and construction engineering and management. We hope that a summary of the Special Issue as provided here will encourage a detailed analysis of the papers included in the Printed Edition.
