If there were no connection, a beam and slab would bend as illustrated diagrammatically below. The presence of a shear connection prevents the slip between the two components and achieves a much stiffer and stronger beam.
Then, the effect of incline angle, mass, and velocity of moving body, layer orientation, load length, and inertial, Coriolis, and centrifugal forces due to the moving distributed mass and friction force between the beam and the moving distributed mass on the dynamic behavior of inclined laminated composite beams are investigated.

Consider an inclined laminated composite beam of length L, width b and thickness h, with the coordinate system placed at the mid-plane of laminate. All orthotropic layers of the laminate are assumed to be of an equal thickness (see Fig 1).
Shear connection in composite bridge beams. From Steelconstruction.info. Jump to: navigation, search. Shear connectors on the top flanges of the steel girders provide the means to achieve composite action between the slab and the girders, thus increasing both stiffness and strength.
