SIMPLIFIED DESIGN OF SHORT-SPAN, ARCH-CULVERT FOOTINGS
Concrete footings used for short-span arch culverts often have a height which is equal to or greater than the footing width. Large eccentricity of loading can occur with variations in footing height versus width, in culvert rise versus span, and in the location of the conduit-to-footing loading point. An analysis procedure is introduced to minimize eccentricity which is patterned after retaining wall overturning and bearing capacity analyses. A simplified chart solution is used to evaluate trial conduit and footing combinations. The trial footing is then verified by the AASHTO loading and "pseudoretaining wall" Culvert-Interaction Method developed for long-span culverts is used as an independent loading and bearing capacity check.
