When torsional cracks occur in the RC element as a result of torsion effects occurring in the structure, the cross-section stiffness decreases by 1/10-1/30 of the stiffness before cracking. When the design codes are examined, it is seen that the reinforced concrete design under the effect of torsion is not sufficiently emphasized. In the study, it is aimed to determine the cross-sectional properties of reinforced concrete elements that will be exposed to torsion effects in accordance with the behavior of the RC element. In this study, reinforced concrete elements with circular, square and rectangular cross-section shapes were modeled in accordance with the cross-section and reinforcement conditions specified in TEC-2007 and analyzed by ANSYS program. The torsional capacities of the elements increase as the cross-sectional area increases. Circular sections exhibit a highly ductile behavior in terms of rotation. Rectangular sections have more stiffness than circular and square sections to torsion.
