Abstract: Two parallel slender beams with visco-elastic interlayer can serve as a relevant mathematical model of a number of engineering systems. A typical example is a double skin facade of tall buildings. The outer skin can be considered as a dynamic damper and thus contribute to comfort inside the building. Many applications emerge in power piping when using two coaxial pipes with an interlayer in order to suppress vibration due to flow and structure interaction. Similar inconvenient behavior can exhibit panels which fall into the flutter post-critical state. Further applications can be expected at industrial chimneys, towers, etc. In principle the idea of vibration damping using such a formation is inspired by very well known tuned mass damper. However its internal structure, function, limitations and singular states are incomparably more complicated and therefore adequate applications should be cautious.
