Semi-active Direct Control of Civil Structure Seismic Responses Using Magneto-rheological Dampers
As building structures frequently collapse and cause losses of lives and properties, due to excessive vibrations induced during earthquake periods, it is crucial to reduce the structural vibrations. This paper develops a Lyapunov-based controller for Magnetorheological (MR) dampers embedded in building structures to mitigate quake-induced vibrations. In this work, MR dampers are used as semi-ac...
متن کاملSemi-active Base isolation System for Buildings using MR Dampers
Due to limitations on the use of passive base isolation systems which show poor performance in near field seismic excitations or active systems which require high external power, as stand alone control devices for a range of seismic excitations, a hybrid control system that mitigates the limitations of either passive or active control systems is preferred. The present study examines the use of ...
متن کاملNon-parametric Models for Magneto-Rheological Dampers
The primary purpose of this chapter is to present an approach for developing nonparametric models for magneto-rheological (MR) dampers. Upon describing the approach adopted here, a non-parametric model for a commercial magneto-rheological damper is developed, and is compared with a parametric model from an earlier study. The results show that the proposed non-parametric model can more effective...
متن کاملReal-time Identification of Magneto-rheological Dampers
Modeling of magneto-rheological dampers to be used in semi-active control of civil engineering structures is addressed. The behavior of this kind of dampers is modeled through a first order Lugre dynamic friction model whose structure is analytically simpler than other dynamic friction models used in the literature. With this structure real-time parametric identification of the magneto-rheologi...
متن کاملOPTIMAL DESIGN OF MAGNETO-RHEOLOGICAL DAMPERS
In the area of semi-active control of civil structures, Magneto-Rheological (MR) damper has been an efficient mechanism for reducing the seismic response of structures. In this paper, an effective method based on defining an optimization problem for designing MR dampers has been proposed. In the proposed method, the parameters of semi-active control system are determined so that the maximum res...
