Experimental Study on Magnetic Fluids Viscous Damper
Key Engineering Materials, 2011Magnetic fluids viscous damper is a new type of dampers, whose structure including magnetic fluids, permanent magnet and a non-magnetic container. Inside the non-magnetic container, magnetic fluids supports the permanent magnet to suspense in it and moves as a working element.

Characterization of Fluid Viscous Dampers for Shock Excitation
2014Fluid viscous dampers (FVDs) are especially attractive for enhancing the performance of the structure subject to dynamic excitation because they not only reduce the deformation demand but also the force demand. The control of transient response of a structure to shock excitations is of interest to various engineering applications.

Fluid Dynamics and Behavior of Nonlinear Viscous Fluid Dampers
Journal of Structural Engineering, 2008Fluid dynamics in viscous fluid dampers with annular orifices was analyzed by solving the Navier–Stokes equations. The shear-thinning effect and viscoelastic behavior of silicone oil, which is often used in a viscous fluid damper, were both considered.

Intensity-Reduced Design for Structure with Fluid Viscous Dampers
Applied Mechanics and Materials, 2014The intensity-reduced method based on fluid viscous dampers is proposed in this study. The analysis model of fluid viscous dampers is firstly introduced. The intensity-reduced design procedure is thoroughly discussed. Taking an 11-story reinforced concrete frame shear-wall structure as example, the intensity-reduced method is implemented in this study.

Special Fluid Viscous Dampers For The Messina Strait Bridge
AIP Conference Proceedings, 2008The Messina Strait Bridge would be the world's longest suspension bridge, with a design earthquake characterised by a PGA value of 0.58 g and a distance between the ipocenter and the bridge of 15 km. Said critical structure of course would need a suitable restraint system for traffic braking loads, wind and seismic actions. Each type of load requires a

Analysis of high-rise building by using fluid viscous dampers
i-manager's Journal on Structural Engineering, 2022Fluid viscous dampers are dynamic actuators that when stroke, it absorb the energy that by tectonic disturbances, wind absorption, or heat on a structure. Every multi-story building structure that is subjected to ground motion in daily life needs to be studied to determine how it responds because this is a common issue for construction. The structure's

Investigation of Impulse Response of an ER Fluid Viscous Damper
Journal of Intelligent Material Systems and Structures, 2009The electrorheological (ER) fluid is a fluid that shows non-Newtonian fluid characteristics when the electrical field is applied. In this study, an experiment of an ER fluid viscous damper, in which an ER fluid is enclosed in the gap of a piston—cylinder system, is carried out to investigate the performances of the ER fluids and the effects of the ...
