Experimental and analytical study of variable fluid damper and stiffness device
A prototype variable fluid damper and stiffness device is evaluated in this study. This damper is capable of providing continuous variation with different levels of system damping and stiffness. The damping and stiffness ...
Analytical study of base-isolated buildings with smart devices: STFT Controller
Elastomeric base isolation systems, consisting of laminated rubber bearings, are very effective in reducing seismic response due to lateral flexibility, which results in longer fundamental period and reduced forces in the ...
Nanocomposite strain sensors: Study of electrical and thermal properties
The strain sensing ability of single-walled carbon nanotubes (SWNTs) in buckypaper are explored using Raman spectroscopy. This sensing ability is also examined based on electrical properties using SWNTs in buckypaper, a ...
Sliding mode control and nonlinear spectra of smart base isolated structures
One of the main challenges in structural design is to protect the structures from the damaging effects of destructive environmental forces such as wind loads and earthquakes. In this research, flexibility and energy ...
Testing and analysis of a prototype fluid damper
A new adjustable damper is evaluated in this study. The damper is capable of providing different levels of damping based on the fluid pressure differential across the piston and fluid flowing through an adjustable orifice. ...
Repetitive control of hysteretic systems using robust H-infinity controller
Unique properties of smart materials have enabled them to successfully replace conventional actuators and sensors. However, their effectiveness and applicability in control is hindered due to the presence of inherent ...
