<p align="justify">The need of structural building system to resist earthquake load will increase in line with the acceleration of infrastructure development in Indonesia. The structural system is not only designed to be strength, stable and ductile, but the structure should be easily repaired after an earthquake. This study examines the new model energy dissipation of steel core frame structure system that was expected to answer the needs of reliable, applicable, and repairable structures. Models of structure was divides into three types, steel structure with core frame which was connected by coupling beam and separated by link, steel structure with core frame which was removed column base, steel structure eccentrically brace frame system. <br /> <br /> The analysis method that was used in this research is linear dynamic analysis, nonlinear static, and nonlinear dynamic. The dummy structure was modeled in Etabs software for elastic design and evaluation of inelastic with Perform 3D. The elastic design of the structure is using the spectrum response method refers to SNI 1726:2012, while the non-linear analysis parameter refers to FEMA 356-2000. Steel grade of material was assumed ST41, it will be modeled in 2 dimensional structure with 20 stories, 4m height per story. The structure has dual core frames that was connected by coupling beams which separate variation links, shear, intermediate and flexure. Link beam define as fuse element, it becomes the weakest element of the structure. To achieve it the structure will be designed with capacity design. Earthquake Spectrum Response is used in Jakarta area in Soft Soil condition. 7 earthquake time history data will be used for nonlinear dynamic analysis that has been adjusted with Jakarta Spectra Response. <br /> <br /> Structural models with dual core frame which was connected coupling beam and separate shear links have better performance than core frame was connected intermediate link and flexural link, either in terms of elastic stiffness, inelastic stiffness, ductility, energy dissipation, and inelastic ultimite capacity.<p align="justify">
