Kata kunci:,GedungKampus, PetaGempa, Response Spectrume, SNI 2010, SNI 2017 Abstract The earthquake became a very important factor in the evaluation of the structure of buildings in Indonesia, because the position of the Indonesian territory lies at the confluence of 3 tectonic plates, namely the Indo-Australian, Eurasian and Pacific plates. In addition, the territory of Indonesia is also traversed by 2 world earthquake pathways, namely the Asia and Pacific earthquake lane, consequently frequent earthquakes occur on a small, medium and large scale. Therefore, building planning must be in accordance with regulations and requirements in Indonesia, namely SNI. Therefore the planning of the Yogyakarta Akprind "Science & Technology" Campus Building Yogyakarta needs to be based on earthquake resistance with a major earthquake factor. This is because the Campus Building is an educational facility that can accommodate many people, so it must be planned to stand firm in the event of an earthquake. The purpose of this research is to know the comparison of inner forces between the 2010 Earthquake Map and the 2017 Earthquake Map as well as knowing the results of the structure analysis of reinforced concrete against the level of security based on SNI 1726: 2012 and using the 2017 Earthquake Map. In this study the analysis was carried out using SAP2000 v.14 software with Response Spectrum method. The results of the analysis show the difference between the Response Spectrum of SNI earthquake map 2010 and SNI earthquake map 2017 is on the parameters of the acceleration of spectrum response of the earthquake of SNI 2010 (Ss = 1.28), (S1 = 0.46), (Sa = 0.85) lower than the acceleration of the response of the earthquake spectrum in SNI 2017 (Ss = 1.7), (S1 = 0.65), (Sa = 1.13). From these results it can be concluded that there was an increase from the 2010 Earthquake Map with the 2017 Earthquake Map, for Ss there was an increase of 24%. For S1 there was an increase of 29% and for the peak acceleration of Sa there was an increase of 24%. Then from the analysis of the portal structure of the plates, beams and columns, it is known that there are different internal forces. These differences occur because the earthquake load generated on each earthquake map is different. In determining the spectral response of earthquake ground acceleration refer to rock acceleration parameters, the amplication factor is related to short period (Fa) vibrations in the period of 0.2 seconds and 1 second period so that the force in the portal plates, beams and columns produced has increased average shear force (BMD) 2.0728% and moments (BMD) 0.5857% on Plates and an increase in shear force (SFD) 1.7437% and moments (BMD) 4.34% on beams and an increase in shear force (SFD) ) 15.1061% and moment (BMD) 26.44% in the column.
