Abstract
An energy-based semi-active control strategy is presented to reduce structural vibration. The equation of motion is derived from a structure-TLCD coupled system. Material and geometrical nonlinearities have been considered in the 3D irregular system. The rigid floors and plan irregularity in the system are assumed. An on-off control orifice is located in the middle of the U-shaped tube TLCD system. The El-Centro 1940 earthquake excitation record is employed to train the algorithm, and two other earthquake excitations are applied to evaluate the performance of the proposed method. The results show that the RMS values of displacement and acceleration responses of the structure reduced significantly under seismic excitations.
