“…The larger system of weight 660 ton is primarily used to mitigate the windinduced vibration of building [4]. Furthermore, many human activity-sensitive structures, such as floors [5][6][7] and pedestrian bridges [4], have been permanently controlled using PTMDs. All of these retrofits were reported to be able to significantly reduce structural dynamic responses.…”

This paper presents a two-stage optimum design procedure for passive tuned mass dampers (PTMDs) to reduce structural dynamic responses with the limitation of PTMD stroke. A new performance index, with the linear combination of structural response ratio and PTMD stroke ratio by a weighting factor alpha, is proposed. alpha ranges from 0 to 1.0. The larger the alpha, the more important the consideration of the stroke. When alpha equals 1.0, the PTMD is locked. The analytical results show that with little sacrifice Of Structural control effectiveness, the PTMD stroke can be significantly suppressed when an appropriate alpha is selected. The numerical simulation of a three-story building under earthquake excitations demonstrated that the proposed optimum PTMD performs as well as the conventional PTMD and its stroke is 30% reduced. Based on the analysis results, it is proved that the new optimum design concept is more flexible and useful in practical application. Copyright (c) 2009 John Wiley & Sons, Ltd

“…These types of dampers also play important roles to deal with structural vibration due to wind, wave and earthquake excitations. Pendulum damper is one kind of passive TMD which has been utilized in many structural vibration control applications [101][102][103]. Pendulum damper is modelled with a large mass that is hung in an oil bath.…”

“…Passive and semi‐active devices have been proposed to add damping to structures such as light‐weight floor systems 3–7 or light‐weight footbridges 8, 9. The performance of these passive devices might be of limited effectiveness if they have to deal with small vibration amplitudes (such as those produced by low‐level human loading) or if vibration reduction over several vibration modes is required.…”

SUMMARY Integral resonant control (IRC) has been recently introduced as a simple, robust and high‐performance technique for vibration control of smart structures instrumented with collocated piezoelectric actuator–sensor pairs. This work deals with the design and implementation of an active vibration control (AVC) system based on an IRC strategy for the mitigation of human‐induced vibrations in light‐weight civil engineering structures, such as floors and footbridges, via proof‐mass actuators. This work presents a new AVC strategy that combines an approximate inversion of the proof‐mass actuator dynamics with an IRC‐based strategy. The result is a control scheme with the following desirable characteristics: (i) the closed‐loop system exhibits very high stability margins, (ii) the risk of stroke saturation at low frequencies is significantly reduced so that the saturation nonlinearity, which has to be included to keep the system hardware safe, can be designed to account only for force saturation (i.e. the actuator performance is enhanced), (iii) rigorous stability analysis and systematic design can be proposed and (iv) it is not necessary to measure the actuator force. The stability analysis is carried out using the recently developed stability theorem based on the positive feedback interconnection of systems with negative imaginary frequency response. The control scheme is validated on a full‐scale prestressed concrete laboratory structure. Excellent vibration reduction performance is reported for frequency‐response‐function‐based tests and for walking excitations. Copyright © 2010 John Wiley & Sons, Ltd.
