In this paper, two hysteretic models are developed to model the flexural and shear responses of columns respectively. The models consist of two distinctive primary curves and a set of loading and unloading rules to describe the cyclic behavior of columns including pinching, stiffness softening, and strength deterioration etc. The shear and flexural responses are coupled together at the element level through equilibrium. The primary curves are generated based on MCFT for constant axial load. The coupled axial-shear-flexural interaction model is implemented as a user element in the FE program, ABAQUS. The model is validated against the experimental results from static cyclic pushover tests and dynamic shaking table tests. The analytical results showed excellent agreement with the experimental results. The model can be used to evaluate the realistic seismic response of a bridge system.
