Abstract

Structural analysis is the science of determining the effects of loads on physical structures and their components. The object used in this study is the Campus Building in Yogyakarta. It has a structure height of 33.9 meters and an area of ± 9864.53 m2. This study aims to analize earthquake load based on SNI 1726:2019. The results of this structural analysis using SAP2000 software. This campus building was formed based on the Special Moment Resistant Reinforced Concrete Frame System (SRPMK). With the quality of concrete, fy = 30 Mpa, the quality of plain reinforcing steel, fy = 235 Mpa, and the quality of screw reinforcement, fy = 392 Mpa. The loading used refers to SNI:1727;2020 for earthquake resistance standards referring to SNI 1726:2019. Based on the results of the dynamic response analysis, it was obtained that the variance requirements were in accordance with mode 1 showing the translational motion in the Y direction, which was 52.4%, mode 2 showing the translational movement in the X direction, which was 52.80%, and mode 3 showing the movement in rotation, which was 54.88. %. The basic seismic shear force of this structure is taken from the largest value of 100% V, the result is that the seismic base earthquake load V = 5878.255 kN. The earthquake direction applied was in the orthogonal direction with a redundancy factor value of 1.3. The deviation between floors does not exceed the allowable limit. The P-Delta effect of the structure concludes that the structure remains stable.
