The chapter will be dedicated in incorporating smart devices to enhance the seismic resilience of the civil engineering structures. The chapter would specifically deal with designing a computationally efficient and adaptive control algorithm with magnetorheological (MR) dampers as control devices, based on response optimization of the structure subjected to seismic excitation. This control strategy also requires fewer structural feedbacks than traditional control systems, making the whole application simple and cost-efficient. Moreover, the whole dynamic range of the MR damper is employed in increasing the compliance of structural control. The performance of the response-based adaptive (RBA) control with single and multiple objective optimizations is contrasted with H2/LQG (where LQG is linear quadratic Gaussian regulator) algorithm. Next, the experimental verification of the RBA control strategy with an MR damper installed on the ground floor is conducted on a five-story framed structure. Details of the shake table, experimental setup, transducers, control hardware, etc., are deliberated. Also, the design, fabrication, and details of the novel power amplifier circuit, which provides the required control current to the MR damper based on control voltage have been discussed. Finally, the proposed semi-active control strategy is compared with passive control strategies (passive-ON and passive-OFF). © 2024 selection and editorial matter, Ehsan Noroozinejad Farsangi, Mohammad Noori, Tony T.Y.
