Abstract
The constant advance in the materials and techniques of civil construction, especially with the advent of the personal computer in the design of structures, allowed the appearance of gradually taller buildings. This resulted in an increase in the slenderness and flexibility of structures, also increasing the vulnerability of these structures to dynamic actions such as winds and earthquakes. In view of this, the vibration control appears as a subject of great importance for structural engineering. One of the passive structural control devices is the Tuned Mass Damper (TMD), which promotes the transference of energy between the main structure and an auxiliary mass. One of the TMD most used in building structures is the conventional pendulum type, but this one still has some drawbacks, such as the large space it occupies inside the building. In this work, a scale model of a 9-store building is controlled by an Inverted Pendulum Tuned Mass Damper (IPTMD). The IPTMD modal parameters, obtained experimentally by video motion capture analysis, are used as the definition basis for main design parameters.
