New Proposal for Seismic Rehabilitation of Hospitals in Cuba

Abstract

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.

Comportamiento Estructural De Una Edificación Esencial De Mediana Altura Usando Aisladores De Base Y Disipadores SLB

“…Otro estudio, propone la rehabilitación de un hospital en Cuba con SLB[11], permitiendo reducir la interferencia durante la rehabilitación y el tiempo de esta. En Lima,[12] evalúan el reforzamiento de un edificio irregular de 14 niveles que no cumple derivas. Finalmente, se elabora un detallado procedimiento de modelado, diseño y análisis de los disipadores a través de los métodos de iteración directa e iteración inversa o fuerza fija[13].…”
