Structural control techniques are widely used to reduce the maximum values of the vibrations caused by strong earthquakes and winds and to rapidly dampen them. Among them, passive control systems have been used effectively to protect structural and non-structural elements from the destructive effects of earthquakes in the past quarter-century. Tuned mass dampers (TMD) that are part of passive control systems have been widely used in civil structures with their alternative benefits. In this study, the optimal adjustment of the parameters of a passive TMD placed on the top floor of the 10-story symmetrical structure was performed by a metaheuristic method called Jaya algorithm. The structural model was modeled in the SAP2000 finite element analysis software to obtain mass and stiffness properties. The results of the numerical analysis showed that the optimization of the TMD parameters is highly effective in reducing the total shear forces of the base of the full-size frame structures and reducing displacement in the event of seismic loads.

The Subject

The chapter introduces developments in intelligent optimal control systems and their applications in structural engineering. It provides a good background on the subject starting with the shortcomings of conventional vibration control techniques and the need for intelligent control systems. Description of a few basic tools required for intelligent control such as evolutionary algorithms, fuzzy rule base, and so forth, is outlined. Examples on vibration control of benchmark building and bridge under seismic excitation are presented to provide better insight on the subject. The chapter provides necessary background for a reader to work in intelligent structural control systems with real-life examples. Current trends in the research area are given and challenges put forward for further research.
