| Abstract | This paper presents the test results of three RC bridge columns with double interlocking spirals under cyclic pure torsion and combined action of cyclic flexural and torsional moments. The damage characteristics of these columns under combined loadings are investigated by extending the existing damage indices for flexural failure mode to pure torsion and combined loading from the perspective of performance-based seismic design. According to various damage limit states, the damage index models under pure torsion and decoupled damage index models for torsion and bending-shear, respectively, under combined loading are developed to evaluate the damage states in terms of progression of damage. Also, the dissipated flexural and torsional energy of three columns for each individual loading cycle and the accumulated dissipated energy with respect to different failure modes are discussed and highlighted, which is an important parameter in assessing the strength and stiffness degradation of reinforced concrete members subjected to cyclic loading. |
