abstract: The well-known Cohesive Crack Model describes strain localization with a softening stress
variation in concrete members subjected to tension. An analogous behaviour is also observed in compression,
when strain localization takes place in a damaged zone and the stress reaches the compressive strength with
surface energy dissipation. In the present paper, we propose the new concept of Overlapping Crack Model,
which is analogous to the cohesive one and permits to simulate material compenetration. The two aforementioned elementary models are merged into a more complex algorithm able to describe both cracking and crushing growths during loading processes in RC members. A numerical procedure based on elastic coefficients is developed, taking into account the proposed constitutive laws in tension and compression. With this algorithm, it is possible to effectively capture the flexural behaviour of RC beams by varying the reinforcement percentage and/or the beam depth
