“…Currently, depending on the working mechanisms, energy-dissipation devices in seismic engineering structures are commonly categorized into friction dampers [1][2][3][4][5][6], metal yield dampers [7][8][9][10][11], viscoelastic dampers [12][13][14], viscous liquid dampers [15][16][17], etc. Traditional dampers usually adopt a particular energy-dissipation mode, most of which lacks a self-centering ability, resulting in the structure of the attached damper being damaged after the earthquake and producing plastic deformation, which is difficult to recover.…”

A mild steel-friction self-centering damper with a hybrid energy-dissipation mechanism (MS-SCFD) was proposed, which consisted of a mild steel, frictional, dual-energy-dissipation system and a disc spring resetting system. The structure and principle of the MS-SCFD were explained in detail while the restoring force model was established. The hysteretic behavior of the MS-SCFD under low-cycle reciprocating loading was modeled. Then, the influence of parameters such as the disc spring preload, the friction coefficient, and the soft-steel thickness on the mechanical properties of the MS-SCFD was investigated. The results indicate that the simulation results are basically consistent with the theoretical prediction results, with a maximum error of only 9.46% for the key points of bearing capacity. Since the MS-SCFD is provided with a hysteretic curve in the typical flag type, it will obtain the capacity of excellent self-centering performance. It can effectively enhance the stiffness, bearing capacity, and self-centering capability of the damper after the pre-pressure of the disc spring is increased. The energy-dissipation capacity of the MS-SCFD increases with the increase in the friction coefficient. However, it also increases the residual deformation of the MS-SCFD. The energy dissipation of the MS-SCFD is particularly sensitive to the thickness of mild steel. After being loaded, all components of the MS-SCFD are not damaged except for the plastic deformation caused by the yielding of the mild steel. The normal function of the MS-SCFD can be restored simply by replacing the mild steel plates after the earthquake. Therefore, it can significantly enhance the economy and applicability of the damper.

“…Javidan et al [29,30] proposed a rotational friction damper joint with an eccentricity from the diagonal of the bay, demonstrating that structural elements remain elastic when using the damper and its application. Among the latest research findings, there is a self-centering rotational friction damper capable of reducing the residual displacement of structures [31,32] and a forceresisting rotary friction damper proficient in efficiently exerting frictional moments [33].…”

This paper explores the strength estimation and hysteretic characteristics of a rotational friction damper with translational movement. The experiment comprised two distinct cases: one involving only rotation and the other allowing rotation combined with translational movement. Notably, in the case integrating translational movement, the load demonstrated an incremental trend aligned with displacement, attributing this behavior to the effect of translational movement. Two strength estimation models were introduced and subsequently benchmarked against both experimental observations and finite element analysis outcomes. The findings indicated a strong alignment between the calculated values derived from the proposed strength estimation model, grounded in work principles, and the observed behavior evident in the test results.
