Comparison of seismic load calculation based on SNI 1726-2012 and SNI 1726-2019 to capacity of elements on low level building

Buildings are designed to resist earthquake loads. After an earthquake occurs, it is expected that buildings will suffer minimal non-structural and structural damage. In designing earthquake loads on buildings, the regulations used in Indonesia refer to SNI 1726-2012. In 2019, the national standardization body (BSN) issued a new standard in carrying out earthquake load planning on building structures. In this standard there is an update on the latest earthquake map based on past earthquake event data. This paper aims to compare those twostandards on low level building in terms of capacity of beams and columns using SAP 2000. The parameter of design spectral response at short periods, S_DS anddesign spectral response at one seconds periods, S_D1 has been increased as well in SNI 1726-2019 especially in Jakarta area, which resulted in greater base shear, story drift, and internal forces on the beam and columns. The analysis result showed that base shear of low-level building has increased by 4,98% in x-axis and 7,21% in y-axis. The internal forces caused by the earthquake load are compared with the cross-sectional capacities of the beams and columns. Since there are not significant changes inS_DS andS_D1 of Jakarta area, the impact on internal forces are minor which leads to result that all beams and columns still below the cross-sectional capacity of the beam and column.
