Research on vibration reduction of high-rise RC frame-shear wall structure controlled by magnetorheological dampers

Abstract

Taking a twelve-layer RCF-SW structure as an example, the three-dimensional calculation model program of uncontrolled and MRD controlled RCF-SW structure was developed by MATLAB software. The simulation results of the model program are compared with those of the finite element model established by ANSYS software. The results show that the three-dimensional calculation model program of uncontrolled and MRD controlled RCF-SW structure can simulate the dynamic response and damping effect of the structure well. The displacement response of the RCF-SW structure controlled by MRD is smaller than those of the uncontrolled structure at the corresponding time, except for individual time periods.
