Banda Aceh city is an earthquake-prone area. One is the phenomenon that a magnitude 9,3 Mw and subsequent tsunami wave occurred in 2004. The incident caused casualties and damage to facilities including educational facilities such as school buildings. After the 2004 Tsunami, affected school was rebuilt insame location as before, therefore necessary to conduct an assessment of school building to ensure safety and comfort of learning process in affected area. The purpose of this study was to determine structure capacity of reinforced concrete school building structure toward earthquake and Tsunami in Banda Aceh, so it can see contruction vulnerability based on table of damage state. Objects in this study was a typical two-story reinforced concrete school buildings in Banda Aceh. The chosen building were SDN 48 and SDN 8. Structures were modelled by using SAP2000 software. Earthquake load data using the2004 Sumatera-Andaman earthquake and Puskim earthquake-predictions which were analyzed using pushover method, and tsunami loads based on the height of inundation at location of school building. As a results, it has been developed capacity curve and spectrum capacity curve to determine damage limit and probability due to earthquake and tsunami hazards. It was found that based on spectrum capacity curve bothschool buildings in slight damage, while based on fragility curve it was found that both school building havea risk of light damage and moderate damage. Based on tsunami load, it has been found that both school building has inter-story drift that exceeds allowable limit, and based on tsunami fragility curve both schoolbuilding were predicted complete damage. © The Authors, published by EDP Sciences.
