“…2 was proposed by Ren [12], and Liu and Liu [13] recently and this non-traditional DVA would be useful in some applications [14]. Based on the fixed-points theory, the optimum tuning parameters of such a vibration absorber had been derived analytically for minimizing the resonant vibration of a SDOF system subjected to force excitation [12][13][14] or caused by ground motions [15]. The optimized non-traditional absorber was shown to have resulted in a larger reduction of the resonant vibration amplitude of the primary mass than the traditional damped dynamic absorber.…”

The H ∞ optimum parameters of a dynamic vibration absorber (DVA) with ground-support are derived to minimize the resonant vibration amplitude of a single degree-of-freedom (SDOF) system under harmonic force excitation. The optimum parameters which are derived based on the classical fixed-points theory and reported in literature for this non-traditional DVA are shown to be not leading to the minimum resonant vibration amplitude of the controlled mass. A new procedure is proposed for the H ∞ optimization of such a dynamic vibration absorber. A new set of optimum tuning frequency and damping of the absorber is derived, thereby resulting in lower maximum amplitude responses than those reported in the literature. The proposed optimized variant DVA is also compared to a ground-hooked damper of the same damping capacity of the damper in the DVA. It is proved that the proposed optimized DVA has better suppression of the resonant vibration amplitude of the controlled system than both the traditional DVA and also the ground-hooked damper if the proposed design procedure of the variant DVA is followed.

SUMMARYIn this study, we propose a new seismic control device, tuned viscous mass damper (TVMD), for building systems. We give a detailed description of an apparent mass amplifier using a ball-screw mechanism, which is one of the most important components for realizing the new device. We also derive a closed-form solution of an optimum seismic control design for a single-degree-of-freedom structure subjected to harmonic excitation. The performance of the new device is compared with those of the conventional viscous damper and viscous mass damper systems. The vibration control system using the TVMD is shown to be the most effective for linear structural systems with dampers having the same additional damping coefficient. The effectiveness of the TVMD for seismic excitation is verified by analyses and shake table tests with a small-scale TVMD.

SUMMARYA variant type of tuned mass damper (TMD) termed as 'non-traditional TMD (NTTMD)' is recently proposed. Mainly focusing on the employment of TMD for seismic response control, especially for base-isolated or high-rise structures, this paper aims to derive design formulae of NTTMDs based on two methodologies with different targets. One is the fixed points theory with the performance index set as the maximum magnitude of the frequency response function of the relative displacement of the primary structure with respect to the ground acceleration, and the other is the stability maximization criterion (SMC) to make the free vibration of the primary structure decay in the minimum duration. Such optimally designed NTTMDs are compared with traditional TMDs by conducting both numerical simulations and experiments. The optimum-designed NTTMDs are demonstrated to be more effective than the optimum-designed traditional TMDs, with smaller stroke length required. In particular, the effectiveness of the TMDs combined with a base-isolated structure is investigated by small-scale model experimental tests subjected to a time scaled long period impulsive excitation, and it is demonstrated that the SMC-based NTTMD can suppress structural free vibration responses in the minimum duration and requires much smaller accommodation space. Additionally, a small-scale shaking table experiment on a high-rise bending model attached with a SMC-based NTTMD is conducted. This study indicates that NTTMD has a high potential to apply to seismic response control or retrofit of structures such as base-isolated or central column-integrated high-rise structures even if only a limited space is available for accommodating TMDs.
