<p align="justify">Nowadays, the construction of high-rise building is a common thing for the community. High-rise buildings are designed with basement that serves as a parking lot. In Indonesia design hight-rise buildings usually use two-stage analysis. We assume that upper strcutre is fixed at the ground level. The basement should be analyzed separately. The basement may cause the structure resulting in larger lateral displacements and longer vibration periode. Distributionof seismic load that occur will different. Thus modeling the upper strucure with basement simultaneously is more recommended in designing high-rise building. However, this method is constrained due to modeling the upper structures and basement simultaneously must consider the effects of soil around the basement. In this study, the design using two-stage analysis with the design using a combined model consider soil structure interaction will be compared. <br /> <br /> <br /> The location of the building is designed to have soft soil conditions and high earthquake acceleration so that the building has a Category Seismic Design D. The building was designed a earthquake-resistant structure with dual system consisting of Special Moment Frame System (SMF) and Special Structural Wall System (SSW). As for the basement the earthquake retaining system used is a combination of Intermediate Moment Frame System (IMF) and Special Structural Wall System (SSW). <br /> <br /> <br /> The modeling of basement was perform using ETABS 2016. Thereafter an earthquake loading analysis was executed using the equivalent static and response spectrum analysis method which referred to SNI 1726-2012.. Structural element design, used by reference SNI 2847-2013.<p align="justify">
