Development of Steel Yielding Seismic Dampers Used to Improve Seismic Performance of Structures: A Comprehensive Review

Abstract

Seismic excitation can cause significant energy to be released within structures. By using special devices, this energy can be consumed and dissipated without deforming structural members significantly. Due to this, structural damage is minimized, casualties are prevented during earthquakes, and structures are extended in their useful life. Over the past five decades, it has been widely acknowledged that steel yielding dampers are among the best energy dissipation devices. It has been stated that the hysteretic behavior of steel yielding dampers could vary slightly depending on their geometry. From a practical point of view, they are suitable for the improvement of seismic safety in new and existing structures. The purpose of this paper is to present a review related to steel yielding dampers, their development, various types, and applications, in order to help understand the role of these dampers in improving the seismic performance of structures. In terms of their shape, steel yielding dampers can be categorized as steel plate dampers, pipe dampers, curved dampers, and slit dampers. The most common use of steel plate, such as ADAS and TADAS, and pipe dampers is within braced frames, whereas U-shaped, Jshaped, and S-shaped dampers are mostly seen in frames with chevron bracing. Steel curved dampers with a 60° angle in a steel-braced frame, on the other hand, provide the best energy dissipation and frame strength. In this direction, until today, steel slit dampers have been found to be the most commonly used steel yielding dampers.

A Review on the Latest Advancements and Innovation Trends in Vibration-Based Structural Health Monitoring (SHM) Techniques for Improved Maintenance of Steel Slit Damper (SSD)

“…SSDs are metal dampers and are considered as a hysteretic type of damping device. Their seismic performance and efficacy in mitigating structural damage and enhancing resilience has been well-established in the recent study conducted by Behnamfar & Almohammadalbakkar in 2023 [13]. In addition, several researchers delved in the seismic performance of an optimized and novel shaped [14], torsional [15] and hysteretic [16], multi-slit [17] and strip [18] metal yielding damper.…”

Seismic Resilience of Steel-Braced Frames Incorporating Steel Slit Dampers: A Review and Comparative Numerical Analysis

“…Fundamentally, the utilization of energy-dissipation mechanisms has been extensively studied and applied in diverse fields [28]. Among these mechanisms, viscous fluid dampers, friction dampers, viscoelastic dampers, and metallic yielding dampers effectively absorb and dissipate energy [29][30][31].…”
