The Increasing of Interface Slip and its Effect on Composite Beams when there Are Cracks in Brittle Material Element

Abstract:

The composite beam is composed of the brittle material element and ductile material element (for example: concrete and steel), and with shear connectors it decreases the slip between the brittle material element and ductile material element, and ensures the coordination and integrity of the cross section. When there are cracks in brittle material element in use, it will increase interface slip. In this paper, we assume that the brittle material has cracks, and calculate the slip of shear connectors. Letting the end slip equal to the ultimate slip of shear connector, the shear force and ultimate moment of composite beam is gotten.
