BEHAVIOR OF SLAB-STIFFENED CULVERT STRUCTURES

Large span elliptical culverts stiffened over the upper portion with a concrete cap can be used economically in highway construction at locations where only a small soil cover is possible. The behavior of such structures based on analyses obtained using the infinite element program ADINA is presented. Primary variables are the thickness of the concrete cap and the depth of the soil. The effects of both the construction sequence and highway loading are considered. The load-carrying mechanism for the composite structure is dependent primarily on the amount of lateral deformation permitted by the adjacent soil and the thickness of the concrete cap. It is concluded that the behavior of the structure is that of a flat arch; but, with the lateral deformations likely to occur, the concrete section should be proportioned as a simple beam.
