A stochastic change detection methodology for reliable monitoring complex nonlinear dynamic systems is proposed. For a semi-active magneto-rheological (MR) damper, the non-parametric, data-driven restoring force method was used to identify the nonlinear dynamic damping device. Both supervised and unsupervised statistical pattern recognition techniques were used to detect the changes in the phys...

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...

The aim of this paper is to study the effectiveness of the passive, active and semiactive versions of the composite tuned mass damper systems to reduce vibrations of building structures exposed to strong winds. The LQR method is used to determine the active and semi-active control forces. Several remarks concerning the effectiveness of considering dampers are formulated on the basis of extensiv...
