Evaluation Findings for Oiles Multiple Viscous Shear Damper (MS-Damper) / Highway Innovative Technology Evaluation Center Staf / Evaluation Findings for Taylor Devices Fluid Viscous Damper / Highway Innovative Technology Evaluation Center HITEC Staff / X Evaluation Findings for Enidine, INC. Evaluation Findings For Oiles Multiple Viscous Shear Damper by Highway Innovative Technology Evaluation avg rating — 0 ratings — published In this paper the authors investigate the dynamic performances of multi-degree-of-freedom shear-type structures equipped with manufactured viscous dampers. The system of added viscous dampers that leads to a mass proportional damping (MPD) matrix is identified as the one providing the best overall performance in terms of minimum top-storey Cited by: Find my institution.

A viscous shear-type damper is provided with a casing including an upper cover which is horizontally movable and a container portion having a rectangular parallelepiped-shaped accommodating space which is covered by the upper cover; an engaging block provided in the accommodating space in such a manner as to be suspended from a lower surface of the upper cover; a plurality of movable. In this study, experiments of cable-damper system were conducted by using a meters long full-scale stay cable. 7 types of mechanical dampers, including oil damper, viscous damper and MR damper. Based on the different approaches to generate damping force, the viscous damper can be classified into two types: rodtype viscous damper [3, ] and viscous damping wall [e]. With regard to. dissipated by viscous dampers and 1/3 by building intrinsic damping. Therefore the additional damping introduced by viscous damper is twice of the intrinsic ing to the energy theory, the equivalent additional damping ratio of the structure will reach to since the intrinsic damping is
Direct, simplified methodologies,, multiple-step approaches, including an efficient five-step procedure,,,, or stochastic-based procedures,,, have been proposed for the evaluation of the seismic response or for a preliminary seismic design of structures with nonlinear fluid viscous dampers. In this paper, attention is restricted to. Viscous dampers have been found to be effective in reducing base shear on bridge piers. However, it is possible that the dampers may add some stiffness to the structure during high-frequency excitations and show viscoelastic behavior beyond the cutoff frequency (Constantinou and Symans, ; Reinhorn et al., ).In contrast to other kinds of dampers, such as viscoelastic dampers, the. It is well known that the design of dampers requires the effective evaluation of maximum seismic velocities or maximum damping forces. according to SEAOC Blue Book , a uniform viscous.
