Análisis de amortiguadores híbridos utilizados en estructuras metálicas de edificaciones de mediana altura para mejorar su respuesta a cargas sísmicas

Abstract

The present research focused on identifying different configurations of hybrid dampers that are applicable to mid-rise buildings through the review of research, these devices were evaluated with computational tools, using the finite element method, which allowed to know the structural behavior of this type of systems with reliable mathematical models. Three types of dampers were identified that use fusible elements such as slits and weak plates to dissipate energy through deformations and contact surfaces that dissipate energy through friction, the analyzed dampers are composed especially of steel plates and surfaces of rough materials joined by bolts forming a single assembly, These devices are then adapted with welded or bolted joints to the structures, especially in the central zone of the beams, thus preventing damage to the structural element and giving way to the formation of ball joints and deformations in the fusible elements. After the analysis, the damper with the most stable behavior was identified in order to propose a proposal to improve the seismic performance and better dissipate the energy of the seismic loads.
