A hypo-elastic FEM based model has been proposed, taking into account the shear-transfer mechanism across the smeared cracks. The induced shear stress on the crack surface generates a slippage resulting in unbalanced forces that can be further redistributed throughout the system. Also, the discrete-crack approach has been used for simulation of the experimentally observed slippage on the contact between the portions with different thickness, as well as for simulation of the uplift and sinking of tested members relatively to the basement. As a result, original software for non-linear analysis of reinforced concrete structures, based on tangent stiffness approach has been developed. Characteristic specimens (columns and shear-walls) have been used for comparison of the analytically obtained results, showing a good agreement with the experimental ones.
