Indonesia is one of the countries with a high earthquake risk, because it is located on the Pacific Ring of Fire, precisely at the intersection of three large tectonic plates. The object of this study is a three-story dormitory building that accommodates many students, so structural reinforcement is needed so that they can save themselves when a disaster occurs. The purpose of this study is to analyze earthquake-resistant beams according to the SNI 1726:2019 reference, so that the beam enlargement is obtained from the initial dimensions of 25 x 50 cm to 40 x 50 cm due to earthquake loads. The longitudinal reinforcement requirements for the supports are 3D19, 2D13, 3D19, while for the field it is 3D19, 2D13, 3D19. For stirrup reinforcement, 2D13 - 100 are needed at the supports and 2D13 - 150 in the field, all of which meet the requirements for flexural, shear, and torsion capacity according to SNI 1726:2019. However, this abstract does not highlight the uniqueness of the research, such as the specific approach taken to meet the requirements of SNI 1726:2019, as well as innovations in research methods or results. In addition, the details of the results are not specific, especially regarding the direct impact of changes in beam dimensions on building safety. The addition of quantitative information, such as structural efficiency or increased flexural and shear capacity, would provide a clearer picture of the contribution of this research to building safety.
