In this report, a lumped-plasticity element model developed by Ibarra et al. (2005) is used to model the behavior of reinforced concrete (RC) beam-columns. The backbone and its associated hysteretic rules provide for versatile modeling of cyclic behavior and, importantly, the model captures the negative stiffness of post-peak response, enabling modeling of the strain-softening behavior that is critical for simulating the collapse of RC frame structures. The outcome of this work is a set of predictive equations that can be used to predict a column's element model parameters for input into analysis models, given the various design parameters of a reinforced concrete column.
