For the same singly-reinforced (reinforcement in tension only) concrete section used in Homework 3, we want to investigate the impact of using a parabolic semi-segment for the shape of the concrete stress-strain curve in the determination of the ultimate capacity of the beam. Note that steel stress-strain behavior will be modeled using elasto-plastic model. The properties of the materials are s"-4500 psi for the concrete and Jy -60 ksi for the reinforcement. Using this type of behavior leads to the...
