Propuesta de modelación numérica de disipadores histeréticos metálicos tipo TADAS, en edificaciones de pórticos de concreto y acero

This article proposes a methodology for modeling TADAS (Triangular Added Damping and Stiffness) metallic hysteretic dampers in moment-resisting concrete and steel frame buildings, which have special energy dissipation capacity. For this purpose, SAP 2000 software was used to carry out the modeling and nonlinear static analysis of progressive plastification of buildings. During the research, the fuse-type behavior of the dampers could be identified, which enter the inelastic range before the structural elements of the main seismic resistance system. In addition, it was observed that the inclusion of these devices in moment-resisting frames improved the capacity of the buildings against lateral loads.
