“…This model is based on a smeared-fixed crack approach and its theoretical basis, deduced for RC membrane elements subjected to general in-plane stresses, can be found in details in [20] and in [24][25][26] in more recently improved formulations. In the uncracked stage, concrete is treated as an elastic non-linear orthotropic continuum, with orthotropic axes coincident with principal stress directions.…”

“…In order not to be bounded to the linear response of materials, we look for the numerical solution of equations (1) to (8) and Figure 3. Aggregate bridging and the bilinear constitutive law of spring (see Cerioni et al, 2011;Rabczuk et al, 2005;Yang and Chen, 2005).…”

A numerical model for analysis of crack appearance and propagation along reinforced concrete bar due to external load with the influence of aggregate bridging is presented. The governing equations are solved by a novel strain-based finite element method. The concrete cover and the reinforcing bar are each modelled separately. The tangential slip between the concrete and the reinforcing bar is fully accounted for, whereas the delamination is neglected. The discrete crack concept is employed, in which the aggregate bridging between two uncracked parts of concrete, separated by a crack, is accounted for by a non-linear spring. The adequacy, accuracy and the efficiency of the present model are verified in studies of reinforced concrete bar subjected to short-term tensile tests. It is found out that by the present numerical model, the spreading of cracks and varying of the length of reinforced concrete bar may be described relatively well. The model also enables the time-dependent analysis of the appearance and propagation of cracks due to restrained shrinkage and creep of concrete.

“…7 is similar to the formula that was suggested by Walraven and Reinhadrt (1981) to investigate shear transfer across crack. Belletti et al (2001) as well as Cerioni et al (2008Cerioni et al ( , 2011 used the aforementioned equation to describe and analysis of the nonlinear behavior of RC membrane elements in framework of smeared crack approach. He and Kwan (2001) used Eq.…”

Cracks and interfaces have been recognized as important planes in global behavior of RC structures. In fact, the response of structures, failure modes and even capacity of RC elements can be affected by the stress transfer mechanism across cracks and interfaces. On the other hand, understanding and expressing different kinds of stress transfer mechanisms has a major role in finite element-based analyses. In this paper, dowel action mechanism has been examined analytically and experimentally. In order to simulate the shear transfer by the dowel bar under different loading conditions, the beam on elastic foundation analogy has been extended by proposing a simple elasto-plastic formulation for subgrade springs. Available experimental results and the data obtained from the experimental program have been used to calibrate and develop the model. Verification of the proposed model is carried out by comparing with the corresponding experimental results.
