Several studies have been done on structural control over the last few decades, with the intent to reduce the structural response of buildings under environmental loads.Generally, the purpose of these works is to mitigate the accelerations and displacements that are generated and compromise the safety of people and the stability of the structure itself.To achieve the desired controlled behavior of the structure, a control device can be used.Among the different existing control alternatives, passive control devices have proven to be very effective and convenient for a structure because they use their own mass to generate inertial forces that counteract the external forces acting on the system.This paper explores the numerical design of a TMDI using a nature-like metaheuristic to find the optimal parameters of the device to implement it in a high-rise building under wind load.For this purpose, the grey wolf optimizer (GWO) is used to reduce the objective functions related to peak displacement and root mean square (RMS) value of acceleration.The results show an important improvement in the response of the building, meaning the displacements and accelerations were mitigated, proving that the TMDI is a suitable device for structural control.
