Enhancing Seismic Performance of Structures through Hybrid Control: Integrating Tuned Mass Dampers and Actuators

EasyChair Preprint 12875

Abstract

This paper presents an in-depth analysis of the seismic performance of a ten-storey single bay steel-framed structure employing a hybrid vibration control system. The study encompasses the modeling and analysis of various vibration control configurations, including a Tuned Mass Damper (TMD) as a passive control mechanism, an active control system utilizing actuators, and the synergistic integration of both active and passive controls. Numerical simulations were conducted using MATLAB Simulink to assess the effectiveness of these control systems. The results indicate promising outcomes, with comprehensive analysis conducted on all pertinent response metrics. Specifically, for the passive control system, a 2% mass ratio yielded the most significant reduction in response among different mass ratios tested (0.2%, 2%, 3%, and 5%). In the active control scenario, optimal performance was achieved with actuators positioned at specific storeys, resulting in notable reductions of 59.34%, 44.30%, and 44.09% for top floor displacement, storey drift, and base shear, respectively. Furthermore, the hybrid control system, integrating actuators at selected storeys and a 2% mass ratio, demonstrated the most effective response reduction, with respective values of 61.94%, 53.51%, and 68.26% for top floor displacement, storey drift, and base shear. Overall, the hybrid control system emerges as the preferred choice considering the desired response reduction and economic feasibility. Future avenues of research include exploring velocity feedback, robust control using LQG, and implementing Genetic Algorithm in MATLAB for further enhancement and investigation of seismic performance optimization strategies.
