摘要: Abstract The stiffness matrix, transfer functions and the corresponding loading vector of a two-layer prismatic Timoshenko beam that includes transversal longitudinal relative displacements along interface, interaction between normal shear stresses effects coupling bending deformations are derived in classical manner. proposed method can be used structural analysis design coupled elements frame systems composite such as simply continuous steel-concrete beams. expressions for load general any type or combination transverse loads fit second-order polynomial curve, including uniformly, trapezoidal parabolic distributed loads. necessary to determine adhesive stresses, axial forces, moments, deflections rotations member also derived. Two comprehensive examples presented show effectiveness validity equations.
