Abstract
High-rise buildings have been becoming higher than never in the last years. Together with this condition came the dissemination of the Pendulum Tuned Mass Dampers (PTMD) as one of the main devices to mitigate induced vibration in this type of structures. Many studies approach variants of control methods, such as passive control, semi-active and others as well as methods for optimized definition of the variables that governs the dynamic behavior of the structure. Despite the technology applied in this type of damping system, its working principle obeys the most fundamental concepts of mechanical vibration. This paper evaluates in a simple manner the dynamic response of a slender metallic frame structure prototype under unidirectional free vibration. The prototype built, followed the design guidelines simulated by FEM (Finite Elements Method). The comparison of the time history acceleration, between the structure without the PTMD and post-implementation of it, shows a significant improvement in structural damping.
