This work presents the seismic evaluation and the rehabilitation proposal of one essential facility, specifically the "Guillermo Luis" hospital of the Moa city in Holguín. The authors intend to apply, for the first time, a non-conventional technique used in Cuba to seismic protection of facilities health. This solution is based on seismic energy dissipation mechanisms, by mean of shear link device. The Shear Link-Bozzo device, allows the "GIRON" precast concrete systems to improve the inadequacies of behavior under earthquake lateral load by avoiding the undesired failure mechanism, such as: weak story and torsion due to great stiffness and mass asymmetries. All the above mentioned aspects drive us to take some alternative measures of seismic retrofit for these typical structures, based on the incorporation of the passive energy dissipation that allows the system to behave in the elastic range of response. By means of this solution it is possible to reduce the interference during the rehabilitation works, and also to reduce the time of break services of the hospital.

Probabilistic assessment expressed through analytical fragility curves of the multifamily housing buildings, located in the southeastern region of Cuba, is presented. Motivated by the latest update of the Cuban code for seismic resistance analysis of structures, NC 46:2017, which has been the object of important changes with regard to the seismic design approaches, the evaluation of the adequacy of existing structures becomes an imperative. Additional reasons that emphasize this need are related to the update of the seismic hazard map for Cuba dated 2017, in which the values of spectral accelerations have been significantly increased, compared to the normative in use at the date of these structures were erected. This fact justifies the seismic reassessment program of a large number of housing buildings located in high-risk areas. To express the structural response under seismic loading, the nonlinear procedures for seismic performance assessment of buildings which combine nonlinear static (pushover) analysis of entire structure and nonlinear response history analysis (NRHA) of an equivalent single-degree-offreedom (SDOF) model have been used. Finally, seismic behavior of one selected structural system through the analytical fragility curves is obtained.
