Indonesia located between two earthquake pathways, Asia Asiatic (Trans Asiatic Eartquake Belt) and the Pacific Earthquake Belt, which has triggered frequent earthquakes in Indonesia. Yogyakarta is one of the cities that was shaken by an earthquake of magnitude 6.3 in 2006.This research conducted an open frame building structure model under earthquake loads using response spectrum, and time history by performing accelogram Imperial Valley on October 15, 1979. The structure analysis was analyzed using SAP2000 software in 3D model. The results of this research are base shear force, story displacement, interstory drift to control the performance of the structural boundaries and the level of structural performance. The analysis results of base shear response spectrum and time history for X direction of 86957,38 kN and 81519,03 kN, while for Y direction is 86631,48 kN and81279,09 kN. The results of nominal deflection response spectrum analysis and time history analysis were 0.679 mm and 0.686 mm. Each analysis is still within the range of the permit value = (0.007hsx) so that the performance of the structure is still in the safe category based on the level of deviation between level and deformation in SNI 1726-2012.
