Abstract:The equation of internal force equilibrium was established for steel-concrete composite beams when they occurred bending deformation under the external loads by using the condition of the equality of interlayer vertical extension on the contact surface. The calculation formula for interlayer shear of steel-concrete composite beams was derived.Comparative analysis of the suggested method and the method from Code GB50017—2003 indicates that the suggested method has a higher calculation accuracy and it is more suitable for practical engineering.

Keywords:steel-concrete composite beam; shear; calculation
