This research aims to find the variations in the shear walls' placement on the structure's response under the Direct Displacement Based Design (DDBD) method. The object of this research is the model of a 10-story reinforced concrete building located in Yogyakarta, Indonesia. Modelling of building structures is carried out in this study with four variations of shear wall placement. First, the walls are located at every building's corner. The shear wall is then positioned in the core of the building, where the apertures have shrunk. Then, the shear wall is located on the edge of the building. Last, the shear wall is located on the edge of the building. ANOVA method is used to analyze the significant difference, i.e., variations in the walls' placement. This research indicates the significant differences in the x-direction shear force and the y- direction moment The shear walls are suggested to be placed according to the building's condition and the earthquake ground site's class to produce an optimal structure to resist earthquake loads.

Therefore, it does not cause casualties or material loss, and building occupants' safety can be relatively guaranteed [1][2]. Lateral loads, especially earthquake loads, are more prone to respond in taller buildings. A particular structural system is needed to withstand earthquake loads and improve buildings' performance. One solution is adding a shear wall [3][4]. However, the beams and columns will be pretty significant when the building is designed without shear walls, and problems will arise at the joints [5]. Furthermore, the presence of the shear wall will affect the building's stiffness so that the lateral forces are not fully borne by the frame structure (columns and beams) [6][7]. In structural engineering, shear walls are structural systems that consist of reinforced concrete slabs (also known as shear panels). It resists the effects of lateral loads acting on a structure. The two results of lateral loads that are commonly designed to be carried by shear walls are wind and earthquake loads [8]. It can be said that shear walls ensure the structure's safety against earthquake loads and other lateral loads. If the primary retaining mechanism (or the only lateral load in a building) is in the wall, then the type of building is called a "shear wall structure" [9]. The use of shear walls can be essential from the economic perspective and the horizontal displacement control. Shear walls are lateral force resisting systems that bear bending moments and shear forces [10].
