Abstract
In this paper tuned liquid column dampers (TLCD) are proposed for suppressing the vertical vibrations of bridges. The conventional TLCD is not suited for damping the vertical vibrations and thus, the configuration has been changed by imprinting a vertical distance of the water level in the static equilibrium position, according to Sun et al. [1]. A novel experimental model setup of a continuous bridge attached with passive TLCDs is presented. Free and forced vibration tests with and without TLCD are performed and several improvements of TLCD parameters are studied. It is shown that TLCDs in a changed configuration are effective damping devices for suppressing the vertical vibrations of bridges. Furthermore the main advantages of TLCDs over classical TMDs are discussed. Based on studies conducted, possibilities of implementing active control systems allowing optimizing the TLCDs eigenfrequency and damping coefficient are presented.
