“…The gigantic measure of energy delivered during a seismic shock can create extraordinary damage, even in modern countries [1]. One of the main challenges in structural engineering design is to reduce the harmful effects of earthquakes by developing new design concepts and techniques [2][3][4]. These devices are meticulously engineered to absorb and dissipate a significant portion of the seismic energy, thereby reducing the force transmitted to the structure.…”

Structures are recommended to be designed and constructed with the integration of structural health monitoring techniques to ensure that they can dissipate a large amount of energy without considerable damage when subjected to earthquakes. Hysteretic (H), friction (F), viscous (V), and viscoelastic (VE) dampers were employed in this study to observe the response of buildings using the commercially available software ETABS. The effect of different dampers along with configurations on three prototype concrete buildings (3, 5, and 10-storey) was studied by performing a time history analysis. Initially, the response of the buildings was observed in terms of storey drifts, base shear, and displacement without using dampers, while gradually increasing the damping ratio from 0 to 40%. Subsequently, the response of the buildings was evaluated in terms of displacements and base shear using various types of dampers with different configurations. The analysis results demonstrated that the effectiveness of viscous and viscoelastic dampers is higher for 3 and 5-storey buildings, while friction and hysteresis dampers are more suitable for 10-storey buildings. This information enables informed decisions regarding the performance and maintenance of dampers, contributing to the overall resilience and durability of structures in seismic events.

“…For more than two decades, structural engineers have worked with innovative structural systems and damping devices as well as smart materials to develop structural damping technologies that can reduce structural damage caused by seismic events. It is well known that passive dampers absorb a considerable amount of earthquake-induced energy using mechanical mechanisms such as yielding of steel materials, friction, fluid inflow, and viscoelastic deformation of solid bodies (Aiken et al, 1993;Kim et al, 2012aKim et al, , 2012bKori and Jangid, 2008;Mazza and Vulcano, 2011;Michael and Constantin, 2014;Mirzabagheri et al, 2015;Mohammad and Hosein, 2015;Neflze and Alp, 2016;Patil and Jangid, 2009;Phocas and Pocanschi, 2003;Saidi et al, 2011;Tani et al, 2009;Teruna et al, 2015;Zhang and Zhu, 2007). Existing passive damping systems are classified into vibration isolation systems, tuned mass damper systems, and story-installationtype damping systems (Soong and Dargush, 1997).…”

A theoretical and experimental investigation of an eccentric rotational channel-type damping system is presented. The proposed damping system can incorporate any type of existing passive dampers and provide a wider field of view to residents compared with existing damping systems. Furthermore, the efficiency of the proposed damping system can be magnified by modifying the geometry of the channel-type secondary system. Cyclic loading and free vibration tests of a full-scale test model with steel dampers were conducted to investigate the validity of the suggested simple behavior prediction model and the vibration characteristics of the proposed damping system. The experimental results were in good agreement with the numerical analysis. The results of numerical prediction studies on a single degree of freedom system with the proposed damping system also showed the effect of the eccentric rotational channel-type damping system on seismic response reduction.

“…The drift capacities of infill walls are around 0.3% -0.5% and ductile structures can have drift capacities up to 4%-5% . The control of structural seismic displacements can be controlled by dampers [1], [2] and [3]. The focus of this paper is given to implement a new type of damper to minimize structural displacements during seismic events.…”
