The tsunami vertical evacuation buildings in Banda Aceh were built after tsunami in 2004. The buildings were intended as one of the mitigation strategies for the community that live in the tsunami prone zone area. The buildings should be designed as a robust structure that can resist the earthquake and tsunami impact. Previously, there were no national standard for the design of tsunami resistant structure. The state of damage buildings that had been considered was only based on the result of an earthquake impact, which include the ground shaking, soil failures, and surface fault ruptures. As the Standard in Indonesia did not cover the tsunami load, it is important to review the capability of the existing vertical evacuation in Banda Aceh. The study is aimed to explore the capability of the existing tsunami evacuation buildings as the vertical evacuation in Banda Aceh. The observation includes the tsunami load assessment of the buildings based on the existing standard that had been used internationally. The existing vertical evacuation buildings in this study is analysed for the performance based on the International standard (The Federal Emergency Management Agency FEMA P646 2012) for tsunami loading impact and the earthquake performance was based on the national standard (SNI 1726 2012). The model of the building structure was generated using software structural anaysis, i.e. SAP2000. The earthquake simulation was based on the 2004 earthquake scenario that input as the dynamic loading. The tsunami loading was analysed using the static analyse. The data of tsunami characteristic such as tsunami inundation and speed were using the data from the existing data and research. The results show that the building needs to be strengthening, as it will suffer the large inter-story displacement in the first and second floors. © 2021 Institute of Physics Publishing.
