“…More recently, the use of multiple TMDs to reduce the peak responses of structures, that are sensitive to torsional effects, has been reported by Jangid and Data (1997), Pansare and Jangid (2003), Li and Qu (2006), Bakre and Jangid (2007) , and Wang et al (2009). The excitations considered in these studies do not differ from those mentioned previously.…”

Use of Tuned Mass Dampers (TMDs) to reduce the wind-induced torsional response of structures has been investigated in the literature by assuming that the wind excitations can be approximated by harmonic forces or white noise random processes; however, such an assumption is not realistic. Further, wind load effects are correlated. This study is focused on the effectiveness of different linear/nonlinear TMDs configurations to reduce the wind induced response. For the analyses, the structure is modeled as a multidegree of freedom system under correlated wind load effects. The results show that the selection of optimum dampers is affected by the consideration of the correlated wind load effects.

“…For representative studies of TMD, ATMD, MTMD and HMD (hybrid mass damper) design, taking into account the effects of transverse-torsional coupled vibration modes, see [Jangid and Datta 1997;Arfiadi and Hadi 2000;Lin et al 2000a;2000b;Ahlawat and Ramaswamy 2002b;Singh et al 2002;Pansare and Jangid 2003;Li and Qu 2006]. It is well known that structures where the center of mass and center of resistance do not coincide will develop a coupled lateral-torsional response when subjected to earthquake ground motions.…”

The application of active multiple tuned mass dampers (AMTMD) for suppressing translational and torsional responses is addressed for a simplified two-degree of freedom structure, able to represent the dynamic characteristics of general asymmetric structures subject to ground motions. By employing the developed optimum parameter and effectiveness criteria of the AMTMD, the influences of the normalized eccentricity ratio and the torsional-to-translational frequency ratio of asymmetric structures on the optimum parameters and effectiveness of the AMTMD are investigated in detail. For comparison purposes, the results of a single active tuned mass damper also are taken into consideration.A list of symbols can be found starting on page 584.

“…To improve the MTMD effectiveness, several optimization procedures are found in literature (Jangid, 1999;Tsai & Lin, 1993;Hoang & Warnitchai, 2005;Magluta et al, 2003;Carneiro, 2004;Li & Qu, 2006). According to Jangid (1999), the optimal parameters of a MTMD cannot be obtained by a procedure similar to that employed by Warburton (1982) for a single damped TMD.…”
