Semi-Active Vibration Control Structure with MR-TLCD under Wind Load

Abstract:

The equation of motion for the coupled system of structure—MR-TLCD is formulated by Lagrange equations in this paper. Wind load response of a single-degree-of-freedom structure with MR-TLCD is obtained by time domain method. From the point of view energy dissipation force of MR-TLCD, the Simple Bi-State (SBS) control algorithm control algorithm is developed based on energy dissipation. By applying semi-active and passive control strategies, the controlled wind load response of the coupled system excited by wind load are numerically simulated. The peak value and root mean square value of the displacement and acceleration are obtained and the control effects of the system using the SBS algorithms. The results showed that the wind load responses of the coupled systems could be controlled effectively by applying the MR-TLCD.
