چکیده
To analyze the multi-dimensional seismic mitigation performance and torsional vibration characteristic of an L-shaped frame structure with a magnetorheological damper (MRD). Firstly, mechanical property MRD is experimentally studied. Then, calculation models without MRDs are found through theoretical analysis, programs compiled. Finally, time history responses calculated during excitation bi-directional wave; displacement, acceleration, story drift ratio, shear force bending moment then compared analyzed. The results show that by adjusting current, damping provided can be adjusted continuously in range 3.1 to 120 kN. compiled model effectively simulate response structure. Reasonable arrangement MR dampers reduce force, moment, vibration, structures.

Modeling and Control of Magnetorheological Dampers for Seismic Response Reduction
Control of civil engineering structures for earthquake hazard mitigation represents a relatively new area of research that is growing rapidly. Control systems for these structures have unique requirements and constraints. For example, during a severe seismic event, the external power to a structure may be severed, rendering control schemes relying on large external power supplies ineffective. M...
متن کامل‘‘Smart’’ Base Isolation Strategies Employing Magnetorheological Dampers
One of the most successful means of protecting structures against severe seismic events is base isolation. However, optimal design of base isolation systems depends on the magnitude of the design level earthquake that is considered. The features of an isolation system designed for an El Centro-type earthquake typically will not be optimal for a Northridge-type earthquake and vice versa. To be e...
متن کاملSeismic Response Study of Asymmetric Systems with Linear and Nonlinear Fluid Viscous Dampers
This investigation is concerned with application of nonlinear fluid viscous dampers for asymmetric-plan systems. For this purpose, the behavior of nonlinear fluid viscous dampers is summarized first followed by the effects of damper nonlinearity on seismic response of asymmetric systems. It is shown that the peak force in nonlinear damper tends to be smaller compared to linear damper. However, ...
