Abstract
The inherent characteristic of concrete tensile cracks, directional nonlocal crack damage, causes so-called rotating
tensile crack damage and softening of compressive strength. In the present study, a plasticity model was developed to describe the
behavior of reinforced concrete planar members in tension-compression. To describe the effect of directional nonlocal crack damage,
the concept of microplane model was combined with the plasticity model. Unlike existing models, in the proposed model, softening
of compressive strength as well as the tensile crack damage were defined by the directional nonlocal crack damage. Once
a tensile cracking occurs, the microplanes of concrete are affected by the nonlocal crack damage. In the microplanes, microscopic
tension and compression failure surfaces are calculated. By integrating the microscopic failure surfaces, the macroscopic failure
surface is calculated. The proposed model was implemented to finite element analysis, and it was verified by comparisons with
the results of existing shear panel tests.
