Seismic Analysis of RC Bridge Columns with Flexure-Shear Interaction

In this paper, modeling approaches describing the hysteretic behavior of reinforced-concrete columns subjected to cyclic deformation reversals are investigated. The inelastic flexure and shear response of a reinforced-concrete column subjected to cyclic deformation is evaluated utilizing lumped hysteretic representations that exhibit efficiency and ease of modeling. The analytical predictions obtained with the new formulations are compared with experimental results from the literature. Comparisons between results with and without shear interaction reveal the importance of the flexure-shear interrelationship and the adequacy of the proposed approach in terms of strength and stiffness predictions.
