This paper presents the seismic vulnerability assessment of a group of schools located in the cities of Medellín, Itagüí and Sabaneta, Colombia, by the use of the Priority Index methodology developed by Hassan and Sözen (1997). The Priority Index allows the identification, among a group of reinforced concrete structures, of those that could suffer severe damage or collapse due to an important seismic event. A details seismic vulnerability assessment should be applied to the identified structures. A total of 82 structures from 30 schools were evaluated in this work. The lateral load resisting system of all of the structures corresponds to reinforced concrete frames with masonry infill. The application of the Priority Index method classified 61% of the analyzed structures with high priority, that is, there is a possibility for those structures to suffer severe damage of collapse in a seismic event. Additional parameters of year of construction and presence of short columns were taken into considerations in this research. Finally 60% of the structures were classified with high priority. Such a high percentage implies that an important number of children are in high risk if a seismic event takes place.

Keywords : Seismic risk; seismic vulnerability; reinforced concrete; schools.
