Numerical Evaluation of Control Force in Rectangular Tuned Liquid Damper

사각형 동조 액체 감쇄장치(TLD)에서 조절하중의 수치적 산정

The properties of Tuned Liquid Damper are investigated theoretically. In this study, numerical model is a nonlinear model for a rectangular TLD under horizontal motion on the basis of the shallow water wave theory, where the damping of the liquid motion is included semianalytically. For TLD subjected to harmonic external force, the liquid motion of TLD is simulated. Analysis result is showed that liquid motion in TLD is strongli nonlinear even under small excitation.
