Non-linear finite element analysis of composite beams with interlayer slips

Geometrically nonlinear analysis of hybrid beam–column with several encased steel profiles in partial interaction

“…During the past decades, several finite element formulations for two-layered beams have been proposed, see for instance [8][9][10][11][12][13][14][15][23][24][25]. It has been found that curvature locking phenomenon occur in low order Bernoulli displacement-based finite element models particularly for short element with stiff shear connector.…”

“…Ranzi et al [22] have proposed a fully nonlinear kinematical model for planar composite beams including longitudinal partial interaction as well as vertical uplift. The co-rotational framework approach was considered by Battini et al [23] and Hjiaj et al [24] for the development of shear rigid [23] and shear deformable [24] beam-column element using the exact local elastic stiffness matrix. Sousa et al [25] developed a materially nonlinear displacement-based finite element model based on a total Lagrangian description considering large displacements, small strains and moderate rotations.…”

Large displacement analysis of shear deformable composite beams with interlayer slips

“…Their model considers fibre-based distributed plasticity approach and was developed within the co-rotational framework. This approach was also considered by Battini et al [30] for the development of beam-column element using the exact local elastic stiffness matrix. In Saje et al [27], a large displacement total Lagrangian formulation for composite beam in partial interaction was developed.…”

Computational Assessment of the Progressive Collapse of a Five Storey Structure Considering Two Different Building Codes

“…Works as Batini et al [15] and Souza et al [16] have demonstrated the importance of considering these effects when analyzing composite structures. Dat and Hai [17] have also demonstrated that catenary effects may play an important role on mitigating PC.…”
