Review of internal force magnitude at the 5-floor hospital in North Sulawesi Province between SNI 1726-2012 and SNI 1726-2019 with response spectrum (2D) method

Guidelines for building structure planning in Indonesia began to be known in the 1970s in PBI‘71 until now. The earthquake loading guidelines begins from special specifications : SNI 1726-2002 to SNI 1726-2019. The latest SNI and its development are affected by the latest findings of National Earthquake study centre which produces an earthquake hazard map for Indonesia in 2017. In this study, the planning method used in the 5-floor hospital building which was located in the Kotamobagu city, and used SNI 2847-2013 as the loading of the structure. It is considered as comparative study since it examined the earthquake load forces using the SNI 1726-2012 and SNI 1726-2019 guidelines. After conducted this study, it was found that there were differences in internal forces in the two planning guidelines. For further studies, it is suggested that the old earthquake-resistant planning guidelines used on the buildings should be reviewed using the new guidelines. Thus, the building’s ability to withstand earthquakes is well examined. The research development on earthquake fractures affects the study of giving review related to earthquake resistance in buildings. Therefore, it is supposed to be carried out periodically.
