| Abstract | Plan asymmetric buildings are very susceptible to earthquake induced damage due lateral torsional coupling. This creates increased force and higher ductility demand on lateral load-resisting elements leading to excessive edge deformations, and sometimes causes pounding between closely spaced adjacent buildings. In general, excessive deformation in asymmetric-plan buildings may be reduced by redistributing the stiffness and/or mass properties to minimize stiffness eccentricity; however, such redistribution may not be always feasible due to architectural and functional constraints. In last two decades researchers have investigated the application of various control devices for seismic response control of torsionally coupled systems. In this paper, the effectiveness of MR damper based control strategies have been investigated for a plan asymmetric system. A one-story and one-way asymmetric building model with rigidly connected MR dampers on two edges parallel to the axes of asymmetry is subjected to unidirectional ground motion. The results of the study show the effectiveness of the control scheme. |
