Abstract

The application of tuned liquid column damper to civil engineering structures was first proposed in 1989. Further analytical and experimental research has been conducted since on its efficiency and improved performance. The studies so far have mainly concentrated on the original tuned liquid column damper (TLCD-I) proposed by Sakai et al. In contrast, little has been done to come up with a comprehensive mathematical modelling reflecting variations to the basic mathematical description given by Sakai et al. This paper describes the damping mechanism of tuned liquid column dampers and its variations through a numerical procedure, and tries to determine how damper characteristics influence the structural response, and to identify optimum damper parameters in order to maximize its efficiency. The second type original tuned liquid column damper (TLCD-II) and the variational tuned liquid column dampers (TLCD-V1 and TLCD-V2) proposed in this report have a higher capacity to control stronger vibrations compare to TLCD-I, hence extending the range of applications for a tuned liquid column damper designed to suppress the structural vibrations induced by environment loads.
