Diseño y construcción de un prototipo de disipador de energía histerético para diseño sismoresistente

Abstract

he present work presents the results of an investigation aimed at designing, constructing and evaluating an economical hysteretic energy dissipator for splicing steel bars, which functions as a ductile fuse, stable, capable of concentrating the damage, avoiding That occurs in the rest of elements of the structure. Conventional seismic designs involve the ability to dissipate energy present in the structural elements, however, this dissipation occurs in a dispersed manner on plastic ball joints that are formed in the structure. What is intended to be achieved is that as a result of the dissipation of energy of the device, it is possible to avoid the creep of the rods that are spliced ​​through it, whereby once the device is integrated within a section Beam or column), the creep of the heatsink is accompanied by the formation of a single crack, which opens or closes during seismic actions that may occur, but in which the damage is centralized mainly in the device having a good capacity Hysteretic, since it dissipates a considerable amount of energy and resists many cycles of inelastic deformation. This research presents the theory, the design criteria, the results of material tests and examples of design of structures with the device which demonstrate the possible advantages of using it. saw.
