A tilted high-rise structure has eccentricity due to its tilted shape, and the deflection caused by gravity load increases the overturning moment. Therefore local damage to members and joints may occur. In this study, a 60-story straight structure and a structure with 12.7 degree-tilted mid-stories to X-axis were modeled to analyze the behavior of models. Linear static analysis was performed to investigate the story drift ratios and the member forces of column and core as the core of the tilted structure moves along the X-axis. The applied load combinations are equivalent static seismic load and gravity load. As a result of the analysis, in the tilted structure, the effect of gravity load was dominant rather than seismic load unlike the straight structure. In addition, as the core moved along the X-axis, the story drift ratio, the axial force of the column, and the area of the core under the tensile force decreased in the load combination including the gravity load. Therefore, it is judged that the core moves along the X-axis is advantageous for structure overturning. However, it is necessary that a detailed review of the stress of the column-beam joint where the load is concentrated.
