Overlap lengths and interlock hooks are automatically taken into account when defining the reinforcement.
In the case of insufficient clamping or overlap length of reinforcement in reinforced concrete elements, the relevant reinforcement moment curvature relationship is not taken into account in the calculation of the section capacity moment.
In the picture below, there is a reinforcement layout shown in a sample beam. Here, the reinforcements that do not provide overlap length in i end, j end and opening regions are not taken into account in moment curvature.
In the picture below, the fiber models to be used in the i end, span and moment curvature analysis at the j end for the beam with reinforcement placement are given.
