“…Due to their high strength-to-weight ratio, high stiffness, and vibration absorption; double-beam systems are widely used in engineering applications such as sandwich or composite beams, multiple-walled carbon nanotubes, aircraft wing spars, tall building, doublebeam cranes, railway tracks resting on elastic foundations, pipelines, bridge spans, and trusses. 1 In some applications, as the main beam is excited, passive vibration control could be achieved by suppressing the undesired vibration by the aid of the auxiliary (secondary) beam. 2,3 Besides, the relative motion of the two beams could play an important role in dissipating the mechanical energy of the system.…”

The stability and free vibration analyses of single and double composite Timoshenko beams have been investigated. The closed-section beams are subjected to constant axially compressive or tensile forces. The double beams are assumed to be connected by a layer of elastic translational and rotational springs. The coupled governing partial differential equations of motion are discretized, and the resulted eigenvalue problem is solved numerically by applying the Chebyshev spectral collocation method. The effects of the elastic layer parameters, the axial forces, the slenderness ratio, the bending–torsional coupling, and the boundary conditions on the critical buckling loads, mode shapes, and natural transverse frequencies have been studied. A parametric study was performed, and the obtained results revealed different features, which hopefully can be useful for single- and double-beam-like engineering structures.
