Analysis of Effect of Crack in Composite Beam on Slip of Shear Connectors

Composite beam takes full advantage of mechanical properties of brittle and ductile materials elements. The key point is to rely on the shear connectors ensure overall coordination of composite beam, so as to achieve the effect of flexural component. The crack in composite beam caused by brittle materials elements is not negligible. We obtained the slip of shear connectors with the second order precision under the conditions that there are cracks in the brittle material elements, and the ultimate moment is obtained too.
