English abstract:
Tuned liquid column damper (TLCD) show excellent energy and vibration absorbing capabilities appropriate
for applications in wind- and earthquake engineering. The objective of this chapter is to
demonstrate the outstanding features of the proposed Tuned Liquid Column Gas Damper (TLCGD)
and present its wide spectrum of applications of three design alternatives. Among others it includes
base isolation of structures, applications to lightly damped asymmetric buildings and other vibration
prone structures like bridges (even under traffic loads) and large arch-dams as well as simple, ready to
use design guidelines for optimal absorber placement and tuning. The evident features of TLCGDs are
no moving mechanical parts, cheap and easy implementation into civil engineering structures, simple
modification of the natural frequency and even of the damping properties, low maintenance costs, little
additional weight in those cases where a water reservoir is required, e.g., for the sake of fire fighting,
and a performance comparable to that of TMDs of the spring-mass- (or pendulum-)-dashpot type.
