Sistema de protección sísmico mediante el uso de disipadores de energía metálicos tipo ADAS para edificaciones de concreto armado.

Abstract

The present work is based on the research and studies carried out on the analysis, design and implementation of energy dissipaters in reinforced concrete buildings around the world. A brief description of the different passive and active energy dissipation systems exists; also the use, advantages and disadvantages of using these elements in buildings where there is a high degree of seismicity. To carry out this study, first, a five-level building of common use is analyzed and designed, provided with a structural system composed of reinforced concrete porticos in both directions. Subsequently, the structure is analyzed from two points of view, with metallic energy dissipators and without metallic energy dissipators. Finally, the reduction of the seismic demand in the structural elements is determined, through the displacements of the mezzanine, using the drift analysis through the SAP2000 program (student version), as well as programs such as Excel and AutoCAD. the analysis of the building. In the first part of this document the generalities, the antecedents, the approach of the problem, the objectives and the justification are defined. The second part describes all the information gathered from research and analysis carried out by different authors, which makes reference to the ADAS-type metallic energy dissipators and the global use of these elements. The third part describes the specific characteristics of the ADAS type energy dissipaters and the different analyzes performed with these elements, as well as the advantages and disadvantages of these. In the fourth part the analysis and modeling of the structure is carried out using SAP2000 (Student version), to determine the level of reduction of the seismic demand of the building. The fifth part presents the most relevant results of this work, the appropriate conclusions and recommendations according to the analysis made previously.
