Fluid viscous dampers for high‐rise buildings

The Structural Design of Tall and Special Buildings, 2003
AbstractUsing supplemental fluid viscous dampers to dissipate energy and reduce building response to dynamic inputs is gaining worldwide acceptance. The concept of supplemental dampers added to a structure is that they absorb much of the energy input to the structure from a transient, not by the structure itself, but rather by supplemental damping ...

Experimental Study on Magnetic Fluids Viscous Damper

Key Engineering Materials, 2011
Magnetic 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.

The dynamic performance of a shear thickening fluid viscous damper

Journal of the Chinese Institute of Engineers, 2014
This paper presents a study of the rheological properties of shear thickening fluids (STF) and the performance of a viscous damper filled with an STF by performing a cyclic loading test. In the rheological test, the STF samples were prepared by blending nanoscale fumed silica powder with polypropylene glycol fluid in different weight fractions. Using a

Characterization of Fluid Viscous Dampers for Shock Excitation

2014
Fluid 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, 2008
Fluid 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, 2014
The 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, 2008
The 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, 2022
Fluid 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

Test Verification of a Design Method for a Fluid Viscous Damper

Advanced Materials Research, 2011
Vibration protection of pipes in nuclear power plants is a critical factor for the safety of the whole plant. In order to improve the anti-shock ability of pipes in nuclear power plants, the application feasibility of the fluid viscous damper in the plant piping protection is investigated. Then a damper design model intended to be used in nuclear power
