Displacement-based nonlinear finite element analysis of composite beam–columns with partial interaction

Full-scale long-term experiments of simply supported composite beams with solid slabs

“…Since then, extensive work has been carried out relying on this model or extending its applicability. For example, some of these studies have focussed on the linear-elastic response of composite beam-columns (e.g., [4][5][6]), the shear deformability of the steel joist (e.g., [7,8]), the derivation of analytical and numerical models to predict the time-dependent behaviour of composite members (e.g., [9][10][11][12][13]) and related finite element (FE) or direct stiffness implementations (e.g., [14][15][16][17][18][19][20]), formulations to account for shear-lag effects (e.g., [21,22]) and their FE applications (e.g., [14,23]), nonlinear material properties (e.g., [24][25][26][27][28]), the nonlinear response in hogging moment regions (e.g., [29,30]), the occurrence of vertical separation between the slab and steel joist (e.g., [31]), the behaviour of timber composite solutions (e.g., [32,33]), making use of thermal prestressing (e.g., [34]), the derivation of analytical models for the partial interaction analysis of multi-layered members (e.g., [35,36]), and the buckling or nonlinear geometric composite response (e.g., [4,[36][37][38]). …”

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.…”

“…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. A large displacement FE model for two-layer beam/column based on shear-rigid Reissner beam theory has been proposed by Hozjan et al [26].…”

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.…”
