“…Steel ring dampers have been extensively used to improve seismic performance of structures. The use of steel ring dampers as passive seismic dampers has been confirmed by several studies [134][135][136][137][138]. Single and dual-ring damper have been sketched in Figure 12(a and b), respectively.…”

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.

“…As such, in recent years, structural engineers have taken advantage of the constructed geometric models as a basis for assessing structural performance [126][127][128][129][130][131][132][133][134][135]. That allows one to improve a decision system for possible actions of the maintenance timely, especially for large-scale complex structures such as bridges [136][137][138][139]. On some occasions, the extracted 3D models were also used as a basis to obtain a calibration for unknown parameters of the structure or components known as inverse engineering [127,140].…”

Over the last decade, particular interest in using state-of-the-art emerging technologies for inspection, assessment, and management of civil infrastructures has remarkably increased. Advanced technologies, such as laser scanners, have become a suitable alternative for labor intensive, expensive, and unsafe traditional inspection and maintenance methods, which encourage the increasing use of this technology in construction industry, especially in bridges. This paper aims to provide a thorough mixed scientometric and state-of-the-art review on the application of terrestrial laser scanners (TLS) in bridge engineering and explore investigations and recommendations of researchers in this area. Following the review, more than 1500 research publications were collected, investigated and analyzed through a two-fold literature search published within the last decade from 2010 to 2020. Research trends, consisting of dominated sub-fields, co-occurrence of keywords, network of researchers and their institutions, along with the interaction of research networks, were quantitatively analyzed. Moreover, based on the collected papers, application of TLS in bridge engineering and asset management was reviewed according to four categories including (1) generation of 3D model, (2) quality inspection, (3) structural assessment, and (4) bridge information modeling (BrIM). Finally, the paper identifies the current research gaps, future directions obtained from the quantitative analysis, and in-depth discussions of the collected papers in this area.

“…These types of dampers are much more economical than indirectly attached dampers in CBF systems. In these categories, the well‐known devices for energy dissipation are the buckling‐related brace (BRB), [ 44–46 ] semi BRB, [ 47 ] U‐shaped damper attached to diagonal brace members, [ 48 ] ring dampers, [ 49,50 ] and box dampers [ 51 ] (generally used as devices that are added directly to diagonal brace members). Although BRB systems have shown good seismic performance, manufacturing the system requires specific facilities and equipment that increase the construction cost.…”

Although concentrically braced frames (CBFs) possess high lateral stiffness and strength, the buckling of compressive members indicates that a system does not have appropriate ductility. Therefore, CBF is not a successful system for high seismic regions. Comprehensive studies have been performed on this drawback concerning CBF systems. The use of a metallic damper is considered an appropriate method to enhance the behavior of CBFs. While metallic dampers improve the hysteretic behavior of the CBF, they impose additional costs on the structures. Therefore, in this study, a steel damper, which is economical and straightforward to construct and replace after a severe earthquake, was developed. The proposed damper was investigated experimentally and numerically. In addition, a parametric study was performed to evaluate the effect of the three types of damper mechanisms (shear, shear-flexural, and flexural) with three types of buckling (elastic, inelastic, and plastic) on the behavior of the proposed damper. The experimental results, as well as the numerical results, indicate that the shear damper exhibits better performance than the other dampers in terms of strength and stiffness. Except in the case where the shear damper is accompanied by plastic buckling, it has a higher energy dissipation capability. In addition, a flexural damper with elastic buckling cannot be considered as an energy-dissipating device because of the fracturing of the damper due to displacement near the elastic zone. Fundamental relationships were used to predict the behavior of these dampers, and these predictions showed good agreement with the finite element results.
