“…As part of the seismic response and dynamic characteristics verification of a steel structure with DFMDs, shaking table tests were conducted on a steel structure with DFMDs under four earthquake ground motion records. It was also confirmed that placement of such X-plate dampers affects the response of buildings in a study by Pujari and Bakre [64]. As compared to the other placement schemes considered, it was reported that the optimal placement of the damoers resulted in a greater reduction of response.…”

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.

“…The aim behind the use of X-shape of damper is it will have a constant strain variationover its height, thus ensuring that yielding occur simultaneously and uniformly over the full height of the damper. XPDs allow it to behave nonlinearly but restrict behavior of the structure up to the linear elastic range.A series of experimental tests were conducted at Bhabha Atomic Research Center (BARC) and IIT Bombay to study the behavior of these XPDs by and Bakre et al (2006) also studied the behavior of XPDs and observed the subsequent results (i) it exhibits smoothly nonlinear hysteretic loops under plastic deformation; (ii) it can sustain a large number of yielding reversals; (iii) there is no significant stiffness or strength degradation and (iv) it can accurately modeled by Wen's hysteretic model or as a bilinear elasto-plastic material. A typical XPD with holding device used in the present work as shown in Fig.…”

In the past it was a common practice to ignore the masonry infill walls in the design of reinforced concrete frame buildings. Many buildings were constructed with open ground storey, resulting in a serious threat when struck by a lateral load like earthquake. Thus, the requirement of seismic strengthening of such buildings was felt all over the world. Various types of energy dissipating devices based on wide range of concepts were explored to seismically strengthen the structures. Metallic damper as an energy dissipating passive device can be very effectively used to address this problem. This paper presents the seismic evaluation of typical ductile designed 5-storey RC building with open ground storey by time history analysis using a computer package SAP2000. A strengthening scheme involving metallic damper is adopted to enhance the performance of the ductile prototype buildings considered in this study.

“…Fujita et al [20] performed a seismic response analysis on piping systems with non-linear support by using a differential algebraic equation and analyzed the effects of the device based on this result. Bakre et al [21,22] established a relevant piping numerical model based on the results of the shake table tests of a piping system that used a sliding friction damper and x-plate damper carried out in 1995 at Tsukuba NIED, Japan, and analyzed these devices' effects on the seismic performance of piping system. Jia et al [23] developed a new type of damper applicable to piping systems and verified it experimentally.…”

Enhancement in the Seismic Performance of a Nuclear Piping System using Multiple Tuned Mass Dampers

In a nuclear power plant, it is essential to improve the seismic safety of the piping system for the coolant transfer to cool the high temperature caused by the nuclear reaction. Under this background, this study makes two major contributions. The first is that though tuned mass dampers (TMDs) were originally used only to reduce the vibration of piping itself, through this research, it was first proved that it had a positive effect on the improvement of the seismic performance of nuclear piping systems. Additionally, this study proposed a design approach that effectively obtains the optimal design values of TMDs associated with seismic performance. In order to effectively derive the TMD optimum design values, we not only utilized the existing TMD optimum design formula, but also additionally proposed a frequency response analysis-based TMD optimal design method. As a result, it was seen that primary responses of system were significantly reduced under the input seismic load due to the use of TMDs for the piping system. It was also confirmed that the use of the existing TMD formula brought about a similar degree of response reduction effect, while it was possible to get the improved effect when using the proposed method.
