“…As is well known, the MTMD with distributed natural frequencies were proposed by [Xu and Igusa 1992] and also investigated by many investigators such as [Yamaguchi and Harnpornchai 1993;Abe and Fujino 1994;Igusa and Xu 1994;Kareem and Kline 1995;Jangid 1995;Li 2000;Park and Reed 2001;Gu et al 2001;Chen and Wu 2003;Kwon and Park 2004;Yau and Yang 2004;Hoang and Warnitchai 2005;Wang and Lin 2005;Lee et al 2006]. The MTMD is confirmed to be capable of rendering better effectiveness and higher robustness in the mitigation of the oscillations of structures in comparison with a single TMD.…”

Lever-type active multiple tuned mass dampers (LT-AMTMD) consisting of several lever-type active tuned mass damper (LT-ATMD) units with a uniform distribution of natural frequencies have been proposed here for the vibration control of long-span bridges under the excitation directly acting on the structure, rather than through the base. The main purpose of selecting this form of excitation is to present guidelines for the buffeting control design of long-span bridges under wind loads. Estimations have been made on the performance of the LT-AMTMD with identical stiffness and damping coefficient and unequal masses for the reduction of harmonically forced vibrations by resorting to the defined evaluation criteria. The LT-AMTMD with the actuator set at the mass block is found to have better effectiveness and higher robustness in alleviating the vibrations of structures in comparison with the LT-AMTMD with the actuator set at any other location. A new major result is that both the spring static and dynamic stretching of the LT-AMTMD with the actuator set at the mass block may be freely adjusted in accordance with the practical requirements by changing the support locations within the viable range while practically maintaining the same performance. Numerical results demonstrate that the LT-AMTMD with the actuator set at the mass block can highly improve the performance of the LT-MTMD (that is, the passive counterpart of the LT-AMTMD) and provide better effectiveness than a single LT-ATMD. Estimations have also been simultaneously carried out on the LT-AMTMD (a single LT-ATMD) with respect to the hanging-type AMTMD (a single hanging-type ATMD) as well as on the LT-MTMD (a single LT-TMD) with reference to the hanging-type MTMD (a single hanging-type TMD), so as to highlight the improved performance of the proposed control system.

“…(28) and (54)) between torsional and vertical bending frequencies susceptible to couple. Table 2 shows the main geometric and dynamic properties, as well as the main dimensionless parameters affecting the wind-structure aeroelastic stability, for some existing cable-stayed bridges: Guamà River Bridge, Brazil (H-shaped towers) [50]; Seohae Bridge, Korea (H-shaped towers) [51]; Jingsha Bridge, China (H-shaped towers) [52]; Tsurumi Fairway Bridge, Japan (inverted-Y-shaped towers) [29]; Yangpu Bridge, China (inverted-Y-shaped towers) [53]; Normandy Bridge, France (inverted-Y-shaped towers) [29]. It can be observed that configurations with inverted-Y-shaped towers can be considered as very similar to AST schemes.…”

This paper deals with the aeroelastic stability problem of longspan cable-stayed bridges under an approaching crosswind flow. Starting from a continuous model of the fan-shaped bridge scheme with both H-or A-shaped towers, critical states of the coupled wind-structure system are identified by means of a variational formulation, accounting for torsional and flexural (vertical and lateral) bridge oscillations. The overall bridge dynamics is described by introducing simple mechanical systems with equivalent stiffness properties and, under the assumption of a prevailing trusslike bridge behavior, analytical estimates for dominant stiffness contributions are proposed. Several case studies are discussed and comparisons with experimental evidences as well as with available analytical and numerical results are presented. The proposed simplified approach proves to be consistent and effective for successfully capturing the main wind-bridge interaction mechanisms, and it could be considered as a useful engineering tool for the aeroelastic stability analysis of long-span cable-stayed bridges.

“…Other advantages of TMD may be lower cost and convenient to operate. However, the application of TMD for flutter control is still limited, and only a few papers on this respect can be found in the literature [6][7][8][9][10]. According to the results obtained through numerical analysis and simple experiments in wind tunnel, these papers indicated that TMDs may also be effective in improving the flutter behavior of bridges.…”

The present study investigated the problem of increasing the critical flutter wind speed of long-span bridges by using tuned mass dampers (TMDs) on both theoretical and experimental aspect. The governing equations of motion of a bridge deck with TMD are analytically formulated. The method of step-by-step flutter analysis is improved and extended from the 2-DOF model to the 4-DOF model to calculate the critical flutter wind speed and parameters of TMD. A sectional model wind tunnel test is carried out to examine and validate the numerical results, and some new findings from the obtained results are included.
