Hybrid Control for Isolation and Energy Dissipation Systems of Flexible Pile
In this paper, a hybrid control system of the energy dissipation and isolation of flexible pile(EDIPF) is proposed, the dynamic analysis model of system is established, and its vibration and control equations are derived. Taking a typical flexible pile base-isolated structure for example, the isolation performance, control effect and main control parameters are studied. The results show that: the isolation and energy dissipation system of flexible pile can effectively reduce the seismic responses of structure, and to apply active control to this system can reduce the possibility of collision between pile and wall of pile hole. At the same time, the vertical loads and the stiffness of superstructure and piles have a significant influence on the control effect of structures.
