Abstract

Abstract

The composite passive control scheme of seismic isolation and tower damping was applied to the twin-tower structure with large-chassis, with the total structural vibration energy minimization as the optimal control objective, the stochastic response expression of the structure was derived, and the optimal control parameters and the influence law of the connecting control parameters on the control effect were analyzed in the equivalent single-DOF simplified model based on the Kanai-Tajimi spectral stochastic ground vibration model, and this parameter was applied to the twin-tower structure with large-chassis. The control effects on the structural response were analyzed in the time domain and frequency domain, and the control effects of the seismic scheme, the seismic isolation scheme and the composite passive control scheme were compared and analyzed to verify the rationality and effectiveness of the composite passive control scheme for the twin-tower structure with large chassis . The results showed that both the isolation scheme and the isolation and absorption composite passive control scheme could play a good control effect on the energy and displacement response of the twin-tower structure with large chassis, and the composite passive control scheme showed a better control effect.
