Monitoring the Inner Force of the Frame-Shear Wall Structure with MR Dampers by FBG Sensors

Abstract:

The experiment system of a three-floor reinforced concrete frame-shear wall eccentric structure has been built based on Matlab/Simulink software environment and hardware/software resources of dSPACE. And then a shaking table test for the hosting structure with and without magnetorheological (MR) dampers is implemented subjected to three different ground motions. The FBG strain sensors were used in this experiment for strains measurement of the columns and monitoring of the appearing and developing of cracks under different stages. The experimental results show that the control strategies of MR dampers have significant effect on axial force of the column.
