Semi-Active Control for Large-Scale Aqueduct by MR Damper
The mechanical model of magneto rheological damper(MRD) is established, and the numerical simulation of seismic responses of aqueduct under earthquake excitation is performed with magneto rheological dampers. The results indicated that the magneto rheological dampers are effective in reducing the aqueduct response, the mitigation rate of semi-active control approaches with the active method The results from the present study may serve as a reference base for seismic design of large-scale aqueducts, and provide theoretical basis of aqueduct using semi-active devices.
