Abstract
Coupling adjacent buildings with supplemental damping devices are a practical and an effective approach to mitigating structural seismic response. In this report two interconnecting adjacent structures supplemented with MR-dampers to reduce the seismic responses are studied..
In the beginning, we use the Bouc-Wen model differential hysteresis model to simulate the MR-damper (3kN) with constant voltage, a random seismic response analysis method for adjacent structures (each was modeled as a single-degree-of- freedom system) coupled with non-linear hysteretic dampers under non-white earthquake excitation is examined.
Through parametric study the features of structural system were examined. Finally, the effectiveness of implementation of MR-damper to the coupling adjacent building is examined for seismic response mitigation on NCREE shaking table test, The two interconnected structure are: one is 6-story and the other is 8-story steel structure, under coupled building control scheme, involving passive-off, passive-on and semi-active control strategies are examined.
Based on the shaking table test, it is observed that installation of MR-damper in the coupling adjacent buildings is a method to control the structural responses of both buildings if the damper capacity and the building characteristics (such as mass, system natural frequency, etc.) are carefully examined.
