Pasar Raya Inpres Block III building in Padang City is a traditional market building that located in the high seismic zone and prone to tsunami. The building consists of five floors that planned to be used as a vertical evacuation for the surrounding community. However, in designing the building structure, it is only planned to strongly against the earthquake load and it does not take into account the tsunami load. In this study, the effect of tsunami load on the building was investigated. This building will be analyzed and modeled by using ETABS v.9.7.1 software. The applied earthquake load in the building refers to SNI 1726:2012, while the tsunami loads refer to FEMA P-646/2012. From the analysis results, it was found that the columns of the building are capable of restrained the tsunami loads, but the beams were not strong enough to withstand the tsunami loads. The beam failure occurred due to the small load-bearing capacity of the beams against the tsunami loads includes buoyant force, additional gravity load, and uplift hydrodynamic force. Furthermore, the retrofitting of the building should be carried out, especially on the beams of the building before being used as a tsunami vertical evacuation building.
