Abstract: In order to accurately calculate the stress and displacement of composite beam under load, based on the elastic mechanics and contact theory, the finite element solution of the beam is derived, in which the effect of shear slip is considered. Using the finite element solution, the deflection and interface shear slip under concentrated loads are calculated. The calculation results are in good agreement with experimental results, which verifies the accuracy and reliability of the finite element solution. This finite element solution provides a new computing tool to analyze the stress and deformation of composite beams with shear slip.

Key words: bridge engineering, composite beam, the finite element method, shear slip, shear stiffness
