Numerical and experimental study of comb-teeth metallic yielding dampers

International Journal of Steel Structures, 2016
In this paper, a new type of metallic yielding damper called comb-teeth damper, CTD, is introduced. CTD is made of steel plates and includes a number of teeth that dissipate energy through in-plane flexural yielding. An optimum geometry of teeth is suggested, which assures uniform distribution of stress along them and prevents strain localization ...

Seismic Behavior of Steel Frames Equipped with Comb-Teeth Metallic Yielding Dampers

International Journal of Steel Structures, 2018
Comb-teeth damper (CTD), is a new type of metallic yielding damper, which is made of steel plates and includes a number of teeth that dissipate energy through in-plane flexural yielding. The behavior of individual samples of CTD have been previously studied numerically and experimentally and it has been shown that this damper has excellent energy ...

Seismic retrofit design method of RC buildings using metallic yielding dampers

, 2020
A study on the seismic retrofit of RC buildings using hysteretic dissipative braces is presented in the paper. By following a displacement-based design procedure, a fully multimodal approach based on an adaptive version of the capacity spectrum method is followed.

Study of an innovative graded yield metal damper

Journal of Constructional Steel Research, 2019
Abstract Metal dampers have been widely used to improve the seismic performance of the building structure. However, conventional metal dampers only possess one yield point and cannot protect the structure efficiently under earthquakes of different intensities.

EXPERIMENTAL STUDY AND APPLICATION OF METALLIC YIELDING–FRICTION DAMPER

Journal of Earthquake and Tsunami, 2013
In this paper, a new idea for designing the metallic yielding–friction damper (MYFD) is presented based on the principle that the metallic plate can be used for yielding and can be the friction component of the passive energy dissipation device (PEDD).

U-shaped metallic-yielding damper in building structures: Seismic behavior and comparison with a friction damper

Structures, 2015
Abstract This paper presents the performance of U-shaped metallic-yielding dampers in steel building frames as well as a comparison with rotational friction dampers, known as Friction Damper Devices (FDD). For this purpose, an installation detail to use a U-shaped damper in steel building frames was suggested.

Shaking table test and numerical analysis of a combined energy dissipation system with metallic yield dampers and oil dampers

Structural Engineering and Mechanics, 2004
A shaking table test on a three-story one-bay steel frame model with metallic yield dampers and their parallel connection with oil dampers is carried out to study the dynamic characteristics and seismic performance of the energy dissipation system. It is found from the test that the combined energy dissipation system has favorable reducing vibration ...
