Implementation of Energy Dissipator, TADAS

Abstract

El Salvador is a country with high seismic demand, so the design and construction processes of buildings today are
aimed at reducing the vulnerability caused by earthquakes, as part of the philosophy of damage mitigation and correct structural performance, there are Advances in detailing and construction techniques, so the use of deformation. energy dissipation systems is a safe way to prevent damage at a reasonable economic cost compared to the use of other more complex and sophisticated technologies. In El Salvador, the implementation of the TADAS (Triangular plate Added Damping And Stiffness) energy dissipation system has been implemented in a pioneering way and on a small scale, in the case of a two-story building, structured with Steel frames with ordinary detailing. The first level corresponds to parking, so the TADAS devices have only been installed in a longitudinal direction, while the second level corresponds to various uses of meeting people in meeting rooms and office work, so architectural issue the existence of windows with a view not interrupted by structural elements turned out to be a condition for not installing TADAS on that level. The final result meets the requirements of the ASCE-7-16 standard in deformation control, and prevention of structural damage due to the ductility that TADAS provides to the global structure. All the structural elements satisfy resistance and service requirements given by AISC-ANSI-36016.
