Horizontal displacement of high-rise buildings with and without basement shear walls

Abstract

Without rigid basement shear walls, high-rise buildings will be weaker, especially when subjected to earthquakes, water, and ground pressure. Designing a basement-filled building increases its rigidity. Research must also analyze basements without shear walls in some buildings. In this paper, the author analyzes the modeling of high-rise buildings and the impact of solid basement shear walls on the top displacement of the building. The study compares buildings with and without solid basement shear walls, considering both the same basement height and different basement heights. The research investigated the performance of the structural system, specifically focusing on the horizontal displacement at the top. Additionally, a numerical analysis was conducted using Etabs software to determine the bending moment, shear force, and axial force at the base of the column. This analysis was performed for a pair of cases: one with shear walls in the basement and another without. Furthermore, the study also considered differences in the height of the basement.
