To analyze the multidimensional vibration reduction performance and torsional vibration characteristics of frame structures with magnetorheological damper (MRD), the space models of the reinforced concrete (RC) frame structure with and without MRD, based on the space beam element and shell element model, are established and programmed by using MATLAB software. Then, comparisons on results of modal analysis and dynamic time history response calculated from self‐programmed space model and finite element model established by ANSYS software are carried out. The comparison results show that the self‐programmed space model is validity and reliability. Finally, the dynamic time history analyses on the structures with and without MRD under bidirectional seismic wave action are presented; the multidimensional dynamic time history response and torsional vibration response between the uncontrolled and the controlled structures are then compared. The comparison results show that MRD can effectively reduce the three‐dimensional displacement response and restraint the torsional vibration response of the space frame structure.

带有磁流变阻尼器的框架结构的多维减振控制

为了分析具有磁流变阻尼器（MRD）的框架结构的多维减振性能和扭转振动特性，基于空间梁单元和壳单元模型，分别对带有或不带有MRD的钢筋混凝土框架结构的空间模型进行了分析。使用MATLAB软件建立和编程。然后，对通过ANSYS软件建立的自编程空间模型和有限元模型计算得到的模态分析结果和动态时程响应进行了比较。比较结果表明，自编程空间模型的有效性和可靠性。最后，给出了双向地震波作用下有无MRD结构的动力时程分析。然后比较了非受控结构和受控结构之间的多维动态时程响应和扭转振动响应。比较结果表明，MRD可以有效地减小三维位移响应，抑制空间框架结构的扭转振动响应。
