“…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.…”

“…As already mentioned, this model, which is based on a smeared-fixed crack approach, was developed for a concrete membrane element containing n reinforcing layers with different orientations, subjected to plane stress conditions. The main features of 2D-PARC, as well as its governing equations can be found in [10][11][12], to which reference is made. In the following Sections the attention will be only focused on the main changes made to the original structure of the model in order to include concrete shrinkage.…”

“…To this aim, concrete shrinkage can be explicitly considered by treating it as a prescribed deformation or as a fictitious force in the analyses [5][6][7][8][9]. In this work, an existing smeared-crack model for RC elements subjected to in-plane stresses, named 2D-PARC [10][11][12], is extended so as to correctly take into account early-age shrinkage effects. In more detail, concrete shrinkage is rigorously modelled by inserting it explicitly into 2D-PARC general algorithm as a prescribed deformation.…”

Shrinkage effects on short-term behavior of reinforced concrete elements are often neglected both in design code provisions and in numerical simulations. However, it is known that their influence on serviceability performance can be significant, especially in case of lightly-reinforced beams. As a matter of fact, the restraint provided by the reinforcement on concrete determines a reduction of the cracking load of the structural element, as well as an increase of its deflection. This paper deals with the modeling of early-age shrinkage effects in the field of smeared crack approaches. To this aim, an existing non-linear constitutive relation for cracked reinforced concrete elements is extended herein to include early-age concrete shrinkage. Careful verifications of the model are carried out by comparing numerical results with significant experimental data reported in technical literature, providing a good agreement both in terms of global and local behavior.

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.

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.
