“…It is difficult to homogenate the values found in other studies since each structure, even if similar, has its own behaviour. In fact, as mentioned in Ghorbanzadeh et al (2021), the efficiency of an SA-TMD "depends entirely on the dynamic characteristics of the structure". In this sense, here the criterium of homogenisation regard the absolute response of the non-damped structure, x s* , with respect the damped structure, x s .…”

Anti-seismic devices are employed to implement the best performance of the structures under earthquakes. In this paper, semi-active tuned mass dampers (SA-TMDs) are studied by considering several combinations of variable friction forces and external disturbances. The variable damping model is used, where the goal consists in estimating the external actions to find the best friction force for system dampening. In particular, general, sinusoidal, and Gaussian dynamic loadings are considered. To obtain the response of the structure and dampers, several numerical solutions have been implemented. Probabilistic and determines analyses have been also developed to study different damper characteristics. Results show that a SA-TMD can reduce the structure displacements up to ~ 70.0% indicating a good performance in controlling different oscillations. This technology not only preserves the integrity of a structure mitigating its vibrations but also improves the life of occupants and their safety and comfort. This is beneficial from the perspective of practical application, and it is an advancement with respect to this theme.

“…Five steel pipe piles with 1.2 m diameter and 15 m length installed at 6 m centre to centre spacing were placed in soil block for modelling of the pile group. Following the American Petroleum Institute (API) recommendation ( 2007) and Ghorbanzadeh et al (2021) , the p-y, qz, and t-z nonlinear backbone curves were derived using Equation 1.…”

“…where, P is the mobilised lateral resistance of single pile, which is obtained as a function of the horizontal pile displacement H y , k is the modulus of subgrade reaction dependent on the internal angle of friction, and the ultimate soil lateral resistance is p u , which can be obtained for wedge failure or flow failure mechanism derived from API recommendation ( 2007), and 1.287 is a coefficient related to cyclic loading, which was defined by Ghorbanzadeh et al (2021) for midrise STMD structures.…”

One of the effective vibration control systems used for structures is the semi active tuned mass damper (STMD), which is popular since it is reliable and simple. STMD characteristics in the design for piled foundations were usually obtained by modelling the foundation raft only to incorporate the soil structure interaction (SSI). However, as it proposed in the recent studies the role of SSI and simulation of piled raft in the analyses proved to be very important in the determination of the STMD parameters. Hence, in this study, efficiency of STMD with respect to the control of seismic response of the structure, was studied by considering the soil-pile-structure interaction (SPSI). Nonlinear time history analysis was applied for a three-layered soil profile including pile foundations by using the well-known substructure (spring) model under two different ground motion records. In order to increase the accuracy of the results, soil profile with piles and building structure with STMD were considered all at once in a single model under the action of seismic loading, named as direct method. P-Y curves which were suggested by American Petroleum Institute (API) were used in the spring method for simulating soil-pile-structure interaction. The results showed that, adjusting the STMD characterizations on piled structures without considering the soil-pile-structure interaction may result to ineffective control of the seismic vibration and in the worst case may lead to amplification of the vibration of buildings.

“…While there are instances of adaptive TMD (Shi et al, 2019), a more comprehensive body of research has focused on the application of semiactive control laws (Casciati and Casciati, 2016;Casciati et al, 2006) to TMD Nagarajaiah and Jung, 2014;Soria et al, 2019;Zelleke and Matsagar, 2019) (STMD). This semi-active inertial device has been studied for different types of structures, such as buildings (Ghorbanzadeh et al, 2021), cables (Casciati and Ubertini, 2008;Li et al, 2022) and footbridges (Casciati et al, 2017;Ferreira and Simões, 2018;Jiménez-Alonso et al, 2021;Soria et al, 2017;Wang et al, 2021). Its use in railway bridges has been studied very superficially (Ferreira, 2013;Luu, 2014) and the robustness of the STMD has not been analysed in-depth when there are uncertainties that are characteristic of this type of structure.…”

Unlike other civil structures, railway bridges commonly experience changes in their operating conditions, such as the introduction of new train models or higher traffic speeds. These changes can lead to the appearance of resonant effects that are not considered in the design stage. To suppress the large vibration of the railway bridges under the train loads, various solutions have been proposed in the literature. One of those is the use of passive inertial controllers or Tuned Vibration Absorbers (also called Tuned Mass Dampers -TMD). However, these devices have a rather narrow bandwidth close to the tuned frequency, making them prone to detuning and losing their effectiveness. This article explores the use of the Semi-active Tuned Mass Damper (STMD) to reduce resonant vibrations of railway bridges under high-speed trains. This device broadens the spectrum of operation of the inertial controller in the frequency domain. Its different effects have been studied throughout this article, being able to conclude that the STMD not only works better in resonance, but also exhibits a higher degree of robustness and a broader operational range within the desired frequency band.
