Building structures located on slopes behave differently than structures located on flat ground because of the different levels of stepped floors made to overcome the slope of the land, resulting in several layers of basements. Also, due to the existence of these steps and the difference in soil level, a retaining wall is often made to hold the soil. The forces acting on the structure consist of those acting on the structure and those acting on the retaining walls, both against gravity loads and against earthquake loads. Often, there is an avalanche force due to the stability of the slopes. The main objective of this research is to: 1) Perform building modelling according to certain assumptions, 2) evaluate the distribution of story-shear forces based on a static and dynamic analysis of building structures, and 3) determine the scale factor based on the distribution of shear forces at the levels of static and dynamic analysis. This paper discusses the structure of a seven-story building with stepped floors, which is then used to calculate a similar structure with 14 levels. The dual system is used to overcome the effect of a smaller floor area on the lower part of the terraces due to the slope of the ground. In this case study, the load due to lateral earth pressure is calculated separately from the building structure with the assumption that the retaining wall, namely the soldier-pile type, can carry the lateral earth pressure as well as overcome sliding due to slope stability. Therefore, the building structure can be designed separately without considering the presence of lateral forces due to differences in soil levels. In the dynamic analysis of the response spectrum, it is advised to obtain a scale factor to compare the basic shear force with the basic shears force of the static analysis. In conclusion, the results of the static and dynamic analysis showed the distribution of the story-shear forces from the first to seventh floors as smaller than those of the eighth floor. Static analysis with ETABS software provides a more rational shear�force solution by level compared to manual static analysis, which assumes cumulative sum. Since the first through seventh floors are semi-basements, a scale factor was taken for the dynamic shear force to the static shear force at the eighth floor.
