    The present experimental work seeks to have a new design alternative to improve the structural response, due to the fact that our area, being located in the fire belt, is prone to suffer damages considered by seismic action. The linear analysis of a conventional reinforced concrete structure was carried out taking into account the requirements for a seismic-resistant structure provided by the NEC-SE-DS standard and the ACI318. In addition, a nonlinear dynamic analysis (time-history) was performed including SLB energy dissipators taking the various parameters provided by the designers. Through this, the following structural responses were compared: drifts, shears, displacements and accelerations between the conventional structure and the structure with the incorporation of SLB dissipators. Also, it should be noted that the first structure was carried out with the design spectrum with reduction factor R=6, while in the structure with the inclusion of dissipaters, 3 pairs of seismic records were used, which were scaled for the same earthquake without the reduction factor. Subsequently, the budget of the conventional structure and the structure with SLB dissipators was obtained taking into account some items used in the construction, which allowed us to make an economic comparison and through this to know the percentage of increase in the cost between the two models proposed. Finally, it is concluded that the SLB energy dissipaters provide a better structural behavior when subjected to a seismic event, decreasing both the drifts and the displacements of the structure; furthermore, these devices dissipate a great amount of energy from the total of the structure, that said, all the damage is received by the dissipaters.
