Resumo
The constant progress of constructive techniques and civil construction materials, coupled with technological advancement, especially in the field of computational simulations, has allowed the construction of increasingly tall and slender structures. These structures presents high flexibility and vulnerability to dynamic loads actions, such as earthquakes, winds and even occupation by human users or machines. Due to this flexibility, these structures commonly suffer from excessive vibration, which can cause users discomfort or compromise the building safety. One of the most used dampers in building structures are the conventional pendulum tuned mass dampers types, but they have the inconvenience of require a lot of internal space inside the building. In this work, a ten-storey shear-building model is analyzed. It is presented a preliminary set of design parameters for an inverted pendulum tuned mass damper (IPTMD), obtained by a Genetic Algorithm optimization analysis.
