Indonesia is an earthquake-prone area. Therefore, it is necessary to design structures against earthquake loads, However, the design process requires skills in using programs like ETABS, and the number of construction experts in Indonesia is still limited. Thus, this research aims to simplify the design process for low-rise buildings based on gravity loads only and with the SMRF requirements. The research method involves parametric studies for variables such as the number of floors and location of the study. The design is conducted based on internal forces calculated by considering only gravity loads, using the approach method in SNI 2847:2019. Then the design is adapted to the SMRF requirement. The design results are then checked for earthquake resistance using ETABS through a linear time-history analysis by comparing the demand obtained from the ETABS analysis with the capacity calculated during the design of structural elements. The result of the study show that for two-story structures, the seismic load is not significantly dominant, whereas for three-story and four-story structures, the seismic load has a significant impact on the structure. Two-story, three-story, and four-story structures designed based on gravity loads only, using the approach method in SNI 2847:2019 and complying with the SMRF requirements, have a maximum D/C ratio of less than one and concluded that two-story, three-story, and four-story strucres designed based on gravity loads only and complying the SMRF requirements are strong in resisting earthquake loads.
