Diseño de estructuras de acero con disipadores viscoelásticos

Abstract

Ecuador is a seismically active territory that in recent decades has presented large-scale movements such as that occurred on April 16, 2016, evidencing that the structures are not suitable to support this type of event. It is for this reason that the traditional design for the capacity implemented in the field of construction must be completed with the inclusion of energy control systems. In order to avoid the collapse of the structures and allow them to remain operational after the seismic event.

The purpose of this titration work is to design a six-story steel structure by implementing linear viscous fluid dissipaters. In order to avoid damage to the structural elements, since the damage will occur in the dissipaters, the methodology of the ASCE 7 standard was followed. The structural elements of the building were divided into moment-resistant frames and gravity frames for the resistance design, applying the AISC 341, the AISC 358 and the AISC 360. Subsequently, the viscous fluid devices were implemented, resulting in a decrease in drifts, displacements, speed, as well as obtaining lower shear stresses in the base
