Experimental Verification of Semi-active Magnetorheological Dampers for Earthquake Structural Control
Magnetorheological (MR) dampers represent one of the most promising semi-active control devices for applications aiming at the seismic risk mitigation of new or existing civil structures. Two 30 kN MR dampers were experimentally tested subjecting them to assigned conventional displacement laws at their ends. The paper describes the main results of the above experimental activity and aims at imp...
متن کاملModeling 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 کاملStructural Control Based on Semi-active Variable Friction Dampers
This paper discusses a methodology of semi-active structural control using a variable friction damper. The presented algorithm is quite simple and straightforward, in which only the slip level of the friction damper is controlled in response to the interstory response velocity of the damperinstalled story so as to maintain the target constant ductility factor. In conducting control there is adv...
متن کاملStudies on Structural Vibration Control with MR Dampers Using Uga
This paper presents a new approach to reducing the seismic responses of spatial structures with magneto-rheological (MR) dampers using Genetic Algorithm with small populations (μGA). μGA is used to obtain the controller for the MR dampers for structural vibration reduction that is difficult to be solved by the classical optimal control. The advantages of μGA are of global property and having li...
متن کاملSemi–active Control of Adaptive Friction Dampers for Structural Vibration Control
Reduction of structural vibrations is of major interest in mechanical engineering for lowering sound emission of vibrating structures, improving accuracy of machines and increasing structure durability. Besides design optimization and passive damping treatments, active structural vibration control can be applied to reduce unwanted vibrations. They become more and more important as lightweight c...
