West Sumatra is listed as one of 18 provinces in Indonesia with the class D seismic design category which is prone to earthquakes and tsunamis. The main causes of earthquakes in West Sumatra include: Subduction Zones of the India-Australia and Eurasia Tectonic Plates, Fault Segments, Mentawai Fault System and Sumatra Fault System. Earthquakes with certain characteristics can cause tsunamis. The rapid propagation of tsunami waves on the mainland coast reaches 25 kilometers per hour with a range reaching 500 meters from the coastline. A vertical evacuation system is needed to reduce the tsunami hazard with a short duration of self-rescue time. With this system, the community is directed to go up to the Temporary Evacuation Place (TES) or shelter with an elevation that is higher than the wave height. In this final project, the West Sumatra Region I Rent Flat I FY 2018 (RSNPP 18-20) located at Padang State University is planned as a shelter with a reinforced concrete structure type. The RSNPP18-20 building consists of 5 floors with a total building height of 5 meters and has a distance of 692 meters from the coastline. In this planning, structural behavior checks in the form of deviation between floors and the ratio of mass capital participation to earthquake loads are carried out. The earthquake load was calculated by analyzing the response spectrum according to the soil data at the site with reference to SNI 1726:2012 and the 2017 Earthquake Hazard and Source Map. After that, the gravity load was added and the internal forces that emerged were then analyzed for structural element reinforcement planning based on SNI 2847: 2013. From the results of the planning, the building was remodeled to be analyzed against the tsunami load by reducing the structural strength by 30%. The calculation of the tsunami load was carried out based on the design regulations for vertical evacuation sites in FEMA P646-508 in 2012. For the tsunami inundation data obtained from the Padang City Inundation Map, while the elevation and distance data were obtained from Google Earth. The design of the structure of the building is calculated as a special moment-bearing frame system structure (SRPMK), including the planning of columns, beams and beam-column relationships with the principle of strong column weak beam. As for the lower structure of the building is planned to use a pile foundation based on soil data with the N-SPT calculation method at the building site.
