By conducting a thorough bibliographic study, it can be seen that there was very little research work in the literature dealing with the problem of shear deformation in short multilayer beams. Especially, these structures are widely used in the construction and building field because of their adaptability, flexibility and the economic and architectural advantages that these can offer. As such, we will treat the buckling behavior of deformable beams in two-layer shear with partial interaction. Timoshenko kinematic assumptions are considered for both the layers. Original closed form analytical solutions of the load and buckling mode of the composite beam under axial compression are derived for various boundary conditions. The presented expressions of the critical loads are consistent with those corresponding to the Euler-Bernoulli beam theory. The proposed analytical formulas will be validated later by 2D finite element calculations.
