<p align="justify">A structural system is designed to be able to carry an excited external load against the system in order to avoid system failure. The earthquake force is one of the external loads that are highly calculated to anticipate. Therefore, as a role in civil engineering, a structural planner or designer must be able to design a structural system that can withstand earthquake load efficiently and effectively. A common method used to anticipate large seismic forces is to use shear walls. Shear walls are usually placed in certain locations that are considered most profitable to the structural system, for example around the emergency stairs and elevators so it can also form a series of walls (core wall). Generally, the shear wall can carry about 75% -90% of the total lateral force depending on the height of the structure, then the rest will still be borne by the frame system itself. Since the proportion of lateral loads held by the shear wall is very large, a small error in the calculation of force within the shear wall can result large percentage of error in the calculation of forces within frames which should be avoided. This research uses two simple structural models of 4 and 10 stories which consists of a series of shear walls and frames, both models of this structure will be loaded with the seismic force calculated using the equivalent static formulation. The structure model will be analyzed using numerical method developed by Kiyoshi Muto and by using finite element analysis method with the help of structural software ETABS version 16.2.0. The analytical results of both structure models will be compared with each other. Through various methods and structural modeling that have been analyzed will be compared several parameters such as moment and shear forces on beams and columns, shear force distribution on shear walls and columns, horizontal and vertical displacement in structural system, and rotation occurring on beams and columns. Both of these methods have different assumptions and simplifications. Analytical results of both methods show no significant difference on the 4 stories structure model, but the difference will be more significant on the 10 stories structure model.<p align="justify"> <br />
