“…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]). …”

“…The present results are compared with the 1-D ones based on Euler-Bernoulli theory (Galuppi and Royer-Carfagni 2012) and the FE results obtained from the software ANSYS, respectively. In the FE model, the beam layers are simulated by the PLANE-183 elements, and the interlayers are equivalent to the distributed Hookean springs (Gattesco 1999;Ranzi et al 2006;Gara et al 2006) simulated by the COMBIN-14 elements. Consider a simply supported two-layer beam subjected to a sinusoidal load, which was studied by Galuppi and Royer-Carfagni (2012) based on the Euler-Bernoulli theory, as depicted in Fig.…”

This paper focuses on the mechanical properties of layered composite beams with viscoelastic interlayers. The exact two-dimensional elasticity theory is used to represent the deformation of each beam layer. The viscoelastic interlayer is described by the MaxwellWiechert model through the quasi-elastic approximation, which greatly simplifies the analytical process. The stress function with a series of undetermined coefficients depending on the time variable is derived for each beam layer. No matter how many layers the beam includes, the total solution can be obtained rapidly and efficiently by using the recursive matrix technique. The present method can give the exact stress and deformation distributions in the beam, which cannot be predicted by the approximate theories such as the one-dimensional Euler-Bernoulli theory. The convergence of the solution is numerically verified. A comparison study indicates that the present results are in agreement with those obtained from the finite element method; however, they have obvious differences from the results based on the Euler-Bernoulli theory for thick beams. Finally, the variations of stresses and displacements with respect to time in a five-layer beam are discussed in detail.

Abstract. This paper presents a displacement -based finite element formulation for nonlinear analysis of steel -concrete composite planar frames subjected to combined action of gravity and lateral loads. A 6DOF super element is proposed for modelling composite beam, allowing for partial interaction between the steel beam and the concrete slab, semi -rigid nature of beam to column composite connection and material nonlinearity. The load control method and the displacement control method are utilized for tracing the structural equilibrium paths, and the direct method is utilized for solving the nonlinear problem. Numerical examples, concerning a two-span continuous composite beam, a portal composite frame and a six -storey composite frame, are performed. The results are compared with experience data or theoretical results from other studies and are discussed for influences of the factors mentioned above on behaviour of composite beams and composite frames.
