“…Both the cases of the structure on uniform, loose sand and layered soil profile result in a fundamental frequency that is greater than the fixed-base frequency of the structure on its own. This stands in contrast to the expectation that additionally imposed soil presence would lower the natural frequency of the system [5,6,9]. This results from the fact that in the centrifuge test the 2-d.o.f.…”

“…Studies into the response of structures considering their interaction with the foundation soil and the TMD have been performed by several authors [2,7,8]. However, prior to Ghosh and Basu [9] very few authors had looked into the effects of altered structural properties as a result of soil-structure interaction (SSI) on the performance of TMDs in seismic vibration control. Ghosh and Basu [9] investigated SSI effects on the TMD performance in a single-degree-of-freedom structure.…”

Nevertheless, their numerical study was based on many simplifications, most notably their assumption of linearity of the soil's stress-strain behaviour.…”

a b s t r a c tTuned mass dampers (TMDs) are widely used to reduce vibrations in structures. However, very little research is available on the experimental investigation of TMDs and their performance in soil-structure systems. In this paper, a series of geotechnical centrifuge tests was conducted to investigate the effects of TMDs on the response of a multiple-storey sway frame structure undergoing dynamic soil-structure interaction (SSI). Structural responses were recorded for a wide range of input motion characteristics, damper configurations and soil profiles. The practicality associated with the use of TMDs in the damping of resonant structures in light of unexpected earthquake characteristics different from design earthquakes was experimentally demonstrated. Tuning a TMD to soil-structure system properties rather than fixed-base structural properties was found to double the improvement in damping and reduce the original peak response by nearly half. The potential effectiveness of a de-tuned mass damper in light of significant SSI was also demonstrated.

“…Studies which investigate the effect of soil in the area of structures equipped with TMD are very limited and small and those few studies can be classified into two categories. In the first category, there are studies conducted on the optimization of TMD parameters [19,21] and in the second category there are studies investigating SSI effect under wind load [4,22] and earthquake load on single-story [23,24] and multi-story structures [25,26]. In 2016, Khoshnoudian et al [20] investigated SSI effects by studying three steel structures with linear behavior and TMD, under the excitation of near-field earthquake.…”

Abstract. During the past two decades, countless and valuable studies have been conducted on passive seismic control of structures on two-dimensional shear frame model and a few on three-dimensional shear frames. To simulate the actual behavior of buildings with higher accuracy, it is necessary to use more realistic and more complex models in evaluating the seismic performance and controller design. In this study, two indicators related to the structural damage and efficiency control have been used for the seismic control of the structure considering the soil-structure interaction (SSI) effect. with a detailed and complex three-dimensional finite element model in the OpenSees software, a twenty-story concrete structure is designed by the performance based plastic design (PBPD) method; the optimization process of control system and structure performance under the circumstances taken into account at the design stage have been studied. Seismic performance subjected to three acceleration records of far-field earthquake has been investigated and to consider the effects of SSI, the simplified cone physical model has been used. Results indicate that according to the type of soil for which the structure is designed, Tuned Mass Damper (TMD) cannot be reliably used to reduce lateral displacement of the structure, but TMD shows a proper performance in reducing inter-story drift

“…It was observed that, as the soil becomes less stiff, considering the relative movement of the foundation and the surrounding soil, the structure-foundation system properties show considerable changes compared to the fixedbase structure. Accordingly, the conventional tuning of the TMD to the natural frequency of the fixed-base structure becomes fairly ineffective to control the vibrational response of the structure subjected to base excitation (Ghosh and Basu 2004).…”

The present investigation illustrates the performance of structure-Tuned Mass Damper (TMD) system to suppress the excessive vibration of structure buildings subjected to near-field ground motions involving the nonlinear effects of three dimensional soilstructure interaction (SSI). Accordingly, three medium-to-high-rise controlled structures based on a shallow mat foundation located on soft to very dense soil are examined. The ground motion database compiled for nonlinear time history (NTH) analyses of the soilstructure-TMD systems consists of an ensemble of 52 near-field ground motions. Comparisons are made in terms of maximum inter-story drift ratio as well as maximum interstory acceleration ratio for the three possible conditions of the foundation: fixed-base structure, linear SSI (LSSI) and nonlinear SSI (NLSSI). The seismic responses of building structures are studied under the variation of key parameters such as peak ground velocity, factor of safety against vertical load bearing of the foundation (F S ), non-dimensional frequency (a 0 ), ground motion characteristic and number of stories. On the one hand, the results indicate that the nonlinear effects of SSI significantly modify the structural responses in comparison with the LSSI counterpart. On the other hand, soil failure decreases the effectiveness of TMD. In a more precise view, it can be demonstrated that installing TMD can suppress the response of structures with linear SSI and without SSI (fixed-base structure) more significantly than that of structures considering NLSSI. Consequently, the responses would generally be underestimated if a linear behavior of the soil is assumed.
