Abstract

India is a developing country and in the construction industry, the need of high rise as well as lighter structures increase continuously. In addition to this, the structures should have also more flexibility and high damping value. The problem of failure increases as height of the structure increases and also serviceability is a major concern. Tuned Liquid Damper (TLD) is applied to reduce the structural vibrations effectively. The main objective of this paper is to show the effectiveness of assumed analytical steel model of given dimension. The building structural vibrations can be minimized using TLD. Two analytical models proposed by Sun and Yu are considered. In Sun’s model, the dynamic equations of motion is solved, whereas in the latter one, the properties of liquid damper are presented by equivalent mass, stiffness and damping ratio modeling the TLD as an equivalent Tuned Mass Damper essentially. An analytical model with the nonlinearity and wave breaking in mind is considered to investigate the response of the frame model, fitted with a TLD. The effectiveness of the TLD was calculated in terms of amplitude of displacements, velocity, and acceleration at top storey of the structure. The model shows the percentage reduction in displacement, velocity and acceleration by 52.77%, 21.17%, and 21.49%, respectively when subjected to a sinusoidal force of magnitude 3 N and frequency ratio (β)=1.
