<![CDATA[The development of infrastructure in Indonesia requires high-rise buildings to be earthquake resistant to ensure the safety and comfort of users. This study aims to examine the upper structure of the Lecture Building which includes the design of reinforced concrete beams, columns and slabs. The analysis was conducted with the guidelines of SNI 1727:2020 for loading, SNI 1726:2019 for earthquake resistance, and SNI 2847:2019 for structural concrete requirements. The research method uses 3D modeling through ETABS 2018 software to calculate internal forces and inter-story drifts. The results of the analysis show that the combined variance mass participation reaches 99%, there are horizontal and vertical irregularities that have been accommodated with the seismic design category D.]]>
