OPTIMUM GEOMETRIC SHAPES OF PRECAST CONCRETE ARCH STRUCTURES OF 24-, 30-, AND 40-FT SPANS (WITH DISCUSSION AND CLOSURE)

PA Rowekamp, JJ Hill, T Krauthammer - Transportation Research Record, 1988 - trid.trb.org
The results of a structural analysis of elliptical-shaped precast concrete arch structures and
circular-shaped arches being considered by the Minnesota Department of Transportation
are summarized in this paper. These arch structures were analyzed to compare the effect of
geometry on structural performance. They were analyzed using the finite element method by
placing identical load conditions on each arch. Half of each arch was modeled, based on
symmetry, with no rotation allowed at the arch crown. The effects of cracking, critical …
