“…One of the earliest theories on the interlayer slip was the analytical model proposed by Newmark et al, 1 who analyzed a two-layer steel-concrete beam with deformable shear connectors by linear Euler-Bernoulli beam theory. Following this work, many interesting analytical models have been developed for studying layered composite beams with interlayer slip, considering two, [2][3][4][5] three, or more layers, [6][7][8][9] Timoshenko two-layer beam, [10][11][12] time-dependent effects, 13 higher order theories, 14 nonlinear or bilinear interface laws, 15,16 2D elasticity, 17 uplift, 18,19 buckling, [20][21][22][23] dynamics, 24,25 curved layered beams, 26 and so forth. Furthermore, the innovative analytical modeling and exact solutions have also been presented of three-layered sandwich and glass plates with compliant inner interlayer by Foraboschi.…”

This paper focuses on the development of a new mathematical model and its analytical solution for the analysis of the mechanical behavior of geometrically and materially linear three-dimensional two-layer bimetallic beams with interface compliance. Consequently, the analytical solution of bending of elastic three-dimensional two-layer composite beams with interface compliance is derived for the first time. In the illustrative example, a three-dimensional two-layer cantilever composite beam made of 6061-T6 aluminum and C83400 red brass is analyzed. It is shown that interface compliance could have a significant influence on the mechanical behavior of such a structure. Finally, the results for different mechanical quantities are tabulated and as such the analytical solution presented can be used as a benchmark solution of three-dimensional bimetallic composite beams.

“…LTB buckling of glass beams made of monolithic and laminated glass was studied by (Luible 2004;Holberndt 2006;Kasper 2005;Belis 2005;Foraboschi 2009;Amadio and Bedon 2010) . All these analytical and experimental studies demonstrated that the load carrying behaviour and also the load bearing capacity not only depends on the geometry, the interlayer shear stiffness and the glass strength but also on geometrical and structural imperfections.…”

There is a growing trend in steel glass facades to maximize the transparency of buildings with structural glass elements e.g. beams, columns, and stiffeners. A relatively new way is the use of glass beams in order to stiffen large glass curtain walls. Although the material glass is a material that is able to resist very high compression stresses, structural glass elements tend to fail because of instability due to their high slenderness. In the past years lateral torsional buckling of glass beams has been studied in many research works. The studies were limited to the fundamental situation of a simple beam without lateral restraint. However, in practice glass beams in glass curtain walls are fixed over the whole length to the front glazing panels by means of structural silicon joints or mechanical fixings. The load carrying behaviour of beams with lateral restraints is different compared to beams with a free lateral displacement. In this work, experimental and theoretical investigations on the lateral torsional buckling of monolithic and laminated glass beams with lateral restraint have been conducted. The objectives were to investigate the load carrying behaviour and to study possible design methods for stability-critical lateral supported glass beams. Finite element simulations were carried out and compared to experimental tests on real size glass beams made of monolithic and laminated glass. The design concept is based on well-known design con

This paper discusses a global buckling analysis approach for sandwich plates with stiffening ribs. The approach is based on theoretical study and is implemented by the finite element method (FEM). The equilibrium equation corresponding to critical global buckling of the sandwich plate with stiffening ribs under simple supported boundary condition is established by the energy method. The critical buckling solutions for a typical rectangular sandwich plate system (SPS) with a single stiffening rib in the longitudinal direction are then investigated while varying the potential influencing factors. The shear rigidity within the inner core exerts little effect on global buckling and can be neglected. An FEM study on elastic buckling was then conducted via ANSYS software. The advantages of the SPS were highlighted via its elastic eigenvalue buckling numerical analysis with multiple stiffeners. The ultimate buckling loads were computed similarly for different influential factors. Finally, an SPS specimen was tested in a compression test. The results showed that when the rib spacing is large, the local buckling of the plates in the grillage is controllable and the SPS is more resistant to both local and global buckling. The results based on our theoretical method agreed well with those of the FEM and experimental results.
