Vibration control of adjacent buildings considering pile-soil-structure interaction

摘要

This paper presents an investigation of the influence of pile-soil-structure interaction (PSSI) on the vibration control of adjacent buildings with pile foundations. With the initial assumption that adjacent buildings are linked by the control actuator of an ideal hydraulic servo-system, based on the Penzien model, the calculation model for adjacent structures with piled foundations considering PSSI is established. The motion and control equations of adjacent structures are then derived, and the influences of PSSI on vibration control of adjacent buildings analyzed. Finally, the influences of soil and structural parameters on structural vibration control are investigated. The results show that the PSSI has an obvious influence on the response of adjacent structures, but little obvious influence on the change in control force. However, the soil and structural parameters, such as shear-wave velocity and pile stiffness, play a significant role in the control process.
