Optimal design of elastic and elastoplastic tuned mass dampers using the Mouth Brooding Fish algorithm for linear and nonlinear structures

A tuned mass damper (TMD) is a vibration control system used to reduce the structural responses earthquakes and extreme wind loads. The performance of TMD depends on its parameters, such as mass, damping coefficient, stiffness. Therefore, several methods have been proposed optimize parameters TMDs. This paper proposes new method for optimizing TMDs' using Mouth Brooding Fish (MBF) algorithm based white noise excitations. effectiveness TMDs optimized other in reducing maximum displacement ten-story linear structure was compared. results indicated that could effectively find optimum TMD. efficacy elastic elastoplastic nonlinear 10-story structures also investigated. According results, optimal more reduced than Besides, exhibited higher efficiency structure.
