“…After these positive outcomes, further research effort should be invested in finding a suitable methodology to determine optimal configurations of distributed multi-actuation systems with partial state information. This is certainly an important and challenging problem, especially for large-scale structures [32,33]. Other related issues of special interest are the study of the potential loss of performance in adjacent actuation devices and the design of decentralized control strategies with partial-state information.…”

Abstract:In this paper, we investigate the design and performance of static feedback controllers with partial-state information for the seismic protection of tall buildings equipped with incomplete multi-actuation systems. The proposed approach considers a partially instrumented multi-story building with an incomplete system of interstory force-actuation devices implemented on selected levels of the building, and an associated set of collocated sensors that measure the corresponding interstory drifts and interstory velocities. The main elements of the proposed controller design methodology are presented by means of a twenty-story building equipped with a system of ten interstory actuators arranged in three different layouts: concentrated, semi-distributed and fully-distributed. For these control configurations, partial-state controllers are designed following a static output-feedback H-infinity controller design approach, and the corresponding frequency and time responses are investigated. The obtained results clearly indicate that the proposed partial-state controllers are effective in mitigating the building seismic response. They also show that a suitable distribution of the instrumented stories is a relevant factor in the control system performance.

“…In their study, the optimization procedures were conducted with genetic algorithm, and the damping coefficients of the added dampers were treated as design variables assigned such that the total damping coefficients used in the structure would be minimal. Sonmez et al also used an artificial bee colony algorithm in their study to obtain the optimal size and location of viscous dampers in planar buildings to reduce the damage to the frame systems during an earthquake. It was observed that the use of the proposed method may be a simple way of solving the problem of optimal damper distribution.…”

Summary In this study, an iterative step‐by‐step procedure is proposed for optimal placement and design of viscoelastic dampers in order to achieve a target damping ratio based on simple equations and quick estimation. Through the procedure, the dampers are placed one by one in stories with maximum interstory drift at each sequence. Effect of lateral stiffness of added dampers and consequent changes in frequency of the structure as well as changes in damping characteristic of the structure after adding each damper are also considered at each sequence. In order to achieve an economical design, dampers are designed according to the lateral stiffness at each story of the main structure instead of using identical dampers in all stories. During the whole procedure, a time‐history analysis is performed at each sequence. Two numerical examples, including an 8‐story and a 15‐story building, are presented. The results indicate that optimal arrangement of dampers has a considerable influence on reduction of roof displacement up to 25% compared to uniformly distributed arrangement of dampers. In addition, with optimal arrangement, the number of dampers needed to achieve a specific interstory drift is significantly reduced, and the structural damping ratio is improved to a target value, reflecting global optimality of the proposed method.

“…Hence, the use of FVDs seems natural for seismic retrofitting where both displacements and forces due to earthquakes are to be decreased. Indeed, optimal design of such dampers for the purpose of seismic retrofitting of frame structures received much attention (Zhang and Soong, 1992;Gluck et al, 1996;Takewaki, 1997;Singh and Moreschi, 2001;Lopez-Garcia and Soong, 2002;Dargush and Sant, 2005;Lavan and Levy, 2005, 2009Aydin et al, 2007;Lavan et al, 2008;Lavan and Dargush, 2009;Adachi et al, 2013;Aguirre et al, 2013;Kanno, 2013;Martínez et al, 2013;Sonmez et al, 2013;Gidaris and Taflanidis, 2014;Hatzigeorgiou and Pnevmatikos, 2014;Lavan and Amir, 2014;Lin et al, 2014;Lavan, 2015). To allow a quick examination of whether such devices are a good alternative, simple methodologies for initial design were proposed as well (FEMA 356, 2000;Palermo et al, 2013;Landi et al, 2014;Rama Raju et al, 2014).…”

Walls and frames have different deflection lines and, depending on the seismic mass they support, may often possess different natural periods. In many cases, wall-frame structures present an advantageous behavior. In these structures, the walls and the frames are rigidly connected. Nevertheless, if the walls and the frames were not rigidly connected, an opportunity for an efficient passive control strategy would arise: connecting the two systems by energy dissipation devices (EDDs) to result in wall-EDD-frame systems. This, depending on the parameters of the system, is expected to lead to an efficient energy dissipation mechanism. This paper studies the seismic behavior of wall-EDD-frame systems in the context of retrofitting existing frame structures. The controlling non-dimensional parameters of such systems are first identified. This is followed by a rigorous and extensive parametric study that reveals the pros and cons of the new system versus wall-frame systems. The effects of the controlling parameters on the behavior of the new system are analyzed and discussed. Finally, tools are given for initial design of such retrofitting schemes. These enable both choosing the most appropriate retrofitting alternative and selecting initial values for its parameters.
