Reducción de la respuesta dinámica de estructuras sismo resistentes con amortiguadores de masa sintonizada

Abstract

The geographic location of Ecuador in the Pacific fire belt, makes seismic phenomena the most dangerous events in its territory. Although the methodology is very sufficient, one of the most accepted seismic protection elements is the use of tuned mass dampers (TMD), which consists of a specific mass, rigidity and damping, which, when coupled and tuned with the main structure, transfers and releases a part of the oscillatory energy induced to the building, reducing unwanted vibrations. This thesis project shows the efficiency of the TMD in controlling the structural dynamic response, when it is applied to idealized structures, as well as existing ones, for harmonic and seismic loads. The application of the TMD is done for a structural matrix of 9 buildings of geometric configuration and variable elevation, all modeled in commercial programs of structural analysis; as well as applied to structures already built, such as the building ¨Orkar Jandl¨, a building belonging to the campus of the Universidad Técnica Particular de Loja.
