Abstract
The aim of the study is to model the non-linear behavior of reinforced concrete beams using the concrete damage plasticity model. The study also investigated the compressive strain relation based on theoretical methods proposed by Carreira and Chu (1985), Hognestad et al (1989) and Kent and Park (1971). The concrete in tension was modelled as linear elastic brittle material with strain softening. The modified stress-strain relationship for linear elastic brittle material with strain softening was suggested by (Said and Mohie, 2012). With respect to the results obtained and summarized, it was observed that the stress-strain curve for the Hognestad model and the Kent and park model had a good agreement. However, at the descending branch, the Kent and park model showed greater softening behavior compared to the hognestad model. The difference in strain softening did not affect the post processing result of the compressive damage.
