Seismic assessment and retrofitting of the old URM railway station building in Padang City, Indonesia

Abstract

The train is one of the means of land transportation between cities that is in demand by all levels of society. As a mass transportation capable of transporting passengers and goods in large quantities and cheaply, the train can be immediately implemented in Padang City, especially from Padang to the Minangkabau International Airport (BIM) in Pariaman regency. To support the program, re-activating the old train stations that are no longer in use such as Pulau Aer Station, should be done by the directorate general of transportation, Indonesia. This station building is located in Southern part of Padang City, Indonesia. This station building is an old unreinforced masonry (URM) building, which had heavily damaged after the earthquake on September 30th, 2009. Before re-activating this station, a building assessment and retrofitting of this station building are required. The building assessment is carried out both visually and through structural analysis, while the building retrofit is designed using the ferrocement layer method. The analysis result shows that the shear stress on the walls of the retrofitted building is able to withstand the working loads, including the earthquake load.
