- Abstract
To study the flexural carrying capacity and failure modes of steel plate-concrete composite continuous slabs, flexural tests and numerical simulation analysis of two composite continuous slabs with different shear connection degrees were conducted. Firstly, the flexural failure experiments of two composite continuous slabs under four-point symmetrical loading were carried out. Then, the finite element software ABAQUS was used to simulate the whole loading process of these composite continuous slabs. The influences of the concrete layer thickness and the bottom steel plate thickness on the flexural carrying capacity of the composite continuous slabs were analyzed. The results indicate that the steel-concrete composite continuous slab first cracks in the negative moment area at the middle support, and then the bending-shear failure occurs in the span. The shear connection between steel plate and concrete decreases from 100 % to 66.7 %, and the ultimate loading capacity of composite continuous slabs decreases by 42.1 %, but their deformation ductility increases slightly. Increasing the thickness of the concrete layer and the bottom plate can improve the flexural ultimate carrying capacity of the composite continuous slabs in different degrees.
