Exposing building façade has led to a magnificent look of the whole building structure creating the assumption of a complicated building structure. Spiral and free form building shape deliver the volatility of the design process not only because of static loading but also dynamic loading such as an earthquake. Modifying an octagon building core throughout its façade by applying an extension cantilever beams and rotating them is the main approach served in this paper establishing a spiral high-rise building. The angle of rotation is varied from 0 to 5 degrees per floor in order to see the stability of the building structure under dynamic loading. The length of the cantilever beam is restrained up to 9 m with the rotating path of an ellipse. The greater the rotation angle, the extreme cantilever beam length in some points. The displacement represents various unpredictable result as the rotation angle livened up as 2-degree and 3-degree rotation angle provides worst. Even though the spiral shape is enormous, the cantilever beam capacity grows critically particularly due to the torsion. Furthermore, reinforcement for the cantilever part must be well confined in order to increase the performance.
