Abstract: The objective of this article is to study the control of the dynamic response of essential structures using SLB device. This type of dissipators has a high initial rigidity that allows it to operate from minimum values of displacement of the structure in the event of an earthquake. The theoretical and practical aspects related to the correct use of these dissipators are explained in detail. The ideal seismic resistance of a structure is that it presents displacements of a rigid system and forces of a flexible system. A rigid - flexible - ductile system presents intermediate responses between a flexible system and a rigid system. The maximum use of this concept in a structure lies in optimizing the use of dissipators and conventional walls to adequately control drifts and at the same time shear forces do not increase considerably in a flexible system. The Anglo-American Clinic was chosen as the existing structure to verify the efficiency of the dissipators. The structure initially presented torsional irregularity and the maximum drifts in both directions exceeded the established limit. With the addition of SLB dissipators on strategically placed decoupled walls, the torsional irregularity was corrected and the maximum drifts were reduced.

Keywords: dissipators, slb devices, structures, reinforcement, torsional irregularity, shear link bozzo.
