The nonlinear behavior of semi-active magneto-rheological (MR) absorbers should be described for improving control algorithms. Also, overheating in the working conditions MR absorber due to current excitation and high damping velocity seriously changes characteristic fluid causes problems controllability. relationship between performance temperature must defined algorithms that when used a syst...

Abstract This paper examines the effect of structural damage on practical/computational identifiability parameters that define nonlinear models building structures subjected to earthquake‐induced base motions. The objective is determine level physical expected successfully estimate restoring force models. For this purpose, analyses aim if a hysteretic (Bouc‐Wen type) model can be identified wit...

Abstract The work describes experiments and models related to auxetic (negative Poisson’s ratio) foams subjected low-frequency variable amplitude 3-point bending loading. A custom vibration test rig is designed used perform the dynamic of PU foam beams within range (1–20 Hz) 5 different displacement amplitudes. tested in this are manufactured using a simplified relatively low-cost uniaxially th...

The nonlinearity behaviour of magnetorheological fluid (MRF) can be described using a number established models such as Bingham and Modified Bouc-Wen models. Since these require the identification model parameters, there is need to estimate parameters' value carefully. In this paper, an optimization algorithm, i.e., Particle Swarm Optimization (PSO) utilized identify models' parameters. PSO alg...

Empruntant ses mécanismes d’élaboration à la fiction, le motif du complot juif constitue chez Albert Cohen l’objet de multiples fictions. La première strate ce se situe dans un discours social fait rumeurs et préjugés. Le Juif y est érigé en bouc émissaire d’une société qui lui attribuant tous les méfaits monde moderne tente rendre l’univers sa lisibilité. Mais s’inscrit aussi imaginaire romane...

The coupling with external mechanical systems such as oscillating masses working tuned mass dampers, dynamic absorbers, elasto-plastic and rigid walls is an effective method to reduce the displacements drifts of structures under loads. An alternative provided by structure independent, auxiliary system. This paper investigates seismic behaviour a rigidly coupled yielding system harmonic ground e...
