INVESTIGATION OF THE OPTIMAL SEMI-ACTIVE CONTROL STRATEGIES OF ADJACENT BUILDINGS CONNECTED WITH MAGNETORHEOLOGICAL DAMPERS
This study investigates the efficacy of optimal semi-active dampers for achieving the best results in seismic response mitigation of adjacent buildings connected to each other by magnetorheological (MR) dampers under earthquakes. One of the challenges in the application of this study is to develop an effective optimal control strategy that can fully utilize the capabilities of the MR dampers. H...
متن کاملHierarchical semi-active control of base-isolated structures using a new inverse model of magnetorheological dampers
Magnetorheological (MR) dampers have received special attention as semi-active devices for mitigation of structural vibrations. Because of the inherent nonlinearity of these devices, it is difficult to obtain a reasonable mathematical inverse model. This paper is concerned with two related concepts. On one hand, it presents a new inverse model of MR dampers based on the normalized Bouc–Wen mode...
متن کاملExperimental 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 کاملFault detection and fault tolerant control of vehicle semi-active suspension system with magnetorheological dampers
In engineering application the sensor or actuator fault will lead to seriously damage to mechanical systems. The research of sensor or actuator fault diagnosis and fault-tolerant control is very important to improve the safety and reliability of the system. The paper investigates the fault diagnosis and fault-tolerant methods of vehicle suspension system with Magnetorheological (MR) dampers (ac...
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...
