Abstract EN
The seismic response of linearly elastic, idealized single-storey, one-way asymmetric building with semiactive magnetorheological (MR) dampers with clipped-optimal algorithm is investigated.
The response is obtained by numerically solving the governing equations of motion.
The effects of eccentricity ratio, uncoupled time period, and ratio of uncoupled torsional to lateral frequency are investigated on peak responses which include lateral, torsional and edge displacements and their acceleration counter parts, base shear, and control forces.
To study the effectiveness of control system, the controlled response of asymmetric system is compared with the corresponding uncontrolled response.
Further, controlled response of asymmetric system is compared with corresponding symmetric system to study the effects of torsional coupling.
It is shown that the implementation of semiactive dampers reduces the deformations significantly.
Also, the effects of torsional coupling on effectiveness of semiactive system are found to be more sensitive to the variation of eccentricity and torsional to lateral frequency ratio.
