Natural hazards such as earthquakes have threatened the life of human beings during the history.As a consequence, the vibration mitigation of structures has caught great importance. Activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. Thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...

Based on the Bouc-Wen model, a nonlinear hysteretic restoring force model is established with dynamic equations. The hardening and softening of material after reaching yield limit are described by force-displacement curve. Gamultiobj algorithm group search optimization (GSO) used to fit identify hysteresis curves, respectively. effectiveness for identifying parameters verified, effects two algo...

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...
