Abstract: A model was recently proposed for predicting the load-deformation response of a reinforced concrete member under torsion combined with bending and shear to spalling or ultimate. This paper shows the application of the model to create interaction surfaces to predict the failure of a member subjected to different ratios of applied torsion, bending, and shear. The model was validated by comparing the predicted and experimental behavior of 28 members from three experimental studies available in the literature. The members were loaded under torsion combined with different ratios of bending, and shear. The torque-twist behavior, reinforcement stress, and concrete surface strain predicted by the model were in close agreement with the experiments. This paper also describes how the model can be applied to create interaction surfaces. The interaction curves predicted by the model were validated by comparing the predicted and experimental capacities of 17 specimens available in the literature.
