“…An online real-time control using a neural network is implemented on a structure fitted with MR dampers [14]. An adaptive control strategy can be a solution to such a problem [15]. The adaptive control system can continuously regulate the output signal to the control device irrespective of the system discrepancies.…”

“…Simpson et al [31] used GAs to find the best location for actuators to monitor the compositional decibel levels in the interior of a framed cylinder structure. Sing et al [15] used a GA to observe and decide where passive control devices should be placed in a multi-story building. To determine the optimum spatial position of actuators in a system, Abdullah et al [10] joined gradient-based optimization and GAs.…”

Most of the studies in the field of structural control are focused on maximizing the performance of control devices without taking into consideration the complex dynamic response of the structure, computational efficiency, performance flexibility, and feedback reliability. Also, the location algorithm of energy dissipation should be concatenated with the control strategy, for effective structural control of multi-story structures. Moreover, in recent years, non-contact measurements using digital image correlation techniques have been adopted and implemented for the monitoring of civil engineering structures. However, its application is restricted to reinforced cement concrete members, involving a lower frequency spectrum, small displacements, and a lower image capture rate. In this study two response-based-adaptive control strategies based on inter-story drift and acceleration response reduction objectives respectively have been proposed. The control strategies are then integrated with the device location algorithm to establish the optimum configuration/location of magnetorheological dampers in addition to the design parameters of the controls system. The performance of proposed strategies is numerically compared with the benchmark Genetic algorithm using the Clipped optimal controller. The corresponding results indicated that proposed control strategies performed better for high-intensity ground motion and satisfactorily for low-intensity records. Next, the shake table results validated the performance of response-based-adaptive control strategies with device allocation algorithm in alleviating the peak and RMS response of the structure. The response of the structure was also attenuated and distributed among the modes of the structure, as indicated by the fast Fourier transform response of the structure.

Summary The aim of this paper is reducing the responses of structures under the mine blast‐induced ground motion by using semi‐active tools. In other words, the objective of this study is to provide a method to reduce the destructive effects of underground mine‐blast excitation. Investigating the behavior of structures under the mine blast excitation is essential because some buildings are subjected to the blast load of mines due to the rapid urbanization in different regions. Also, the importance of studying this excitation, based on the distinctive nature of mine blast‐induced underground motion, becomes more apparent. For proper investigation and comparison of responses, a seismic excitation is considered. To reduce the responses of two proposed shear structures, magnetorheological (MR) and orifice dampers are utilized. The optimum location for these dampers is investigated. To generate the optimal force each time step the clipped‐optimal algorithm is used based on the input force. The control force can be changed by adjusting the input voltage and magnetic field of dampers. In this research, structural responses based on optimal and maximum voltage are scrutinized. The results indicated that the proposed method is appropriate for reducing the responses of structures under the mine blast‐induced ground motion and seismic excitation.
