Abstract：In order to analyze the multi-dimensional earthquake mitigation performance and the torsional vibration characteristics of the frame structure with Magnetorheological Damper (MRD). Based on the beam elements model, the spatial beam element calculation model of MRD controlled frame structure is established. Taking a ten-story Reinforced Concrete (RC) frame structure as an example, the spatial beam element calculation model programs of the RC frame structure with and without MRD were developed by MATLAB software. The dynamic time history analysis is carried out under the earthquake load. The displacement, acceleration response of typical nodes in X, Y, Z direction and the spatial torsional vibration response of structure is compared under uncontrolled and controlled frame. The results show that: MRD can effectively reduce the displacement and acceleration time history response of the RC frame structure. If the damper position is not set properly, the torsional vibration response of the structure will be increased. The results verify the validity of the spatial beam element calculation models and the MATLAB program of the MRD controlled frame structure.
