Application Research of MR Damper for Aqueduct Seismic-resistance

The mechanical model of magneto rheological damper was established,and the numerical simulation of seismic responses of aqueduct under earthquake excitation was performed with magnetorheological dampers. The results indicated that the magnetorheological dampers are effective in reducing the aqueduct response. 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.
