“…Rashid, 1968;Č ervenka and Gerstle, 1971;Bažant and Oh, 1983;De Borst, 1986;Rots and Blaauwendraad, 1989), there are not many descriptions of their successful combination in the literature. Owen et al (1983) presented a combination of cracking and viscoplasticity. Comprehensive treatise of the problem was provided also by De Borst (1986), and several works have been published on the combination of damage and plasticity (e.g.…”

“…Because of the symmetry, a quarter of the slab is modelled, and a 3 × 3 mesh, which is used to model the quarter of the slab, is Cross-section Layer System also shown in Figure 2. The de ections at node 2 were calculated from the present element, and compared with those obtained from experiments [26] and with the degenerated thick shell element by Owen et al [27] in Figure 3, where it can be seen that the results produced by the current element are good.…”

SUMMARYA new 3-node, 18-DOF triangular layered plate element is developed in this paper for the geometric and material non-linear analysis of isotropic plates and reinforced concrete slabs under service loads. The proposed model is a combination of Allman's 3-node, 9-DOF triangular membrane element with drilling degrees of freedom and the reÿned non-conforming 3-node, 9-DOF triangular plate-bending element RT9 in order to account for the coupling e ects between membrane and bending actions. The element is modelled as a layered system of concrete and equivalent smeared steel reinforcement layers, and perfect bond is assumed between the concrete layers and the smeared steel layers. The maximum normal stress criterion is employed to detect cracking of the concrete, and a smeared ÿxed crack model is assumed. Both geometric non-linearity with large displacements but moderate rotations and material non-linearity, which incorporates tension, compression, concrete cracking and tension sti ening, are included in the model. An updated Lagrangian approach is employed as a solution strategy for the non-linear ÿnite element analysis and a numerical example of reinforced concrete slab is given to demonstrate the e cacy of this robust element.

“…A more accurate description of the nonlinear behaviour of concrete has been provided in the framework of the finite element method (see Owen and Hinton 1980 for a wide overview on computational aspects), where several models based on plasticity (Pramono and Willam 1989;Owen et al 1983;De Borst 1986) or on a combination of damage and plasticity (Simo and Ju 1987;Grassl and Jiràsek 2006) have been proposed. However, as pointed out by Morley (2008), the application of plasticity theories does not allow the study of size-scale effects, in spite of their apparently successful applications over a wide range of structures of ordinary size.…”

An integrated cohesive/overlapping crack model for the analysis of flexural cracking and crushing in RC beams

In the present paper, a new fracturemechanics based model is proposed for the analysis of reinforced concrete beams in bending describing both cracking and crushing growths taking place during the loading process by means of the concept of strain localization. In particular, the nonlinear behaviour of concrete in compression is modelled by the Overlapping Crack Model, which considers a material interpenetration when the elastic limit is overcome, in close analogy with the Cohesive Crack Model, routinely adopted for modelling the tensile behaviour of concrete. On the basis of different nonlinear contributions due to concrete and steel, a numerical finite element algorithm is proposed. According to this approach, the flexural behaviour of reinforced concrete structural elements is analyzed by varying the main geometrical and mechanical parameters. Particular regard is given to the role of the size-scale effects on the ductility of plastic hinges, which is available at the ultimate load conditions.
