Lilac Road Overcrossing, a 695' long concrete arch bridge, with box-shaped ribs and superstructure, was designed using several cross-sectional configurations of variable depths. One of the box sections employed consisted of top and bottom slabs with a middle, or stiffener slab which traverses between the three girders. This section, of variable depth, will be used near the center of the bridge. The designer requested analysis to determine the distribution of forces into the middle slab under dead, live, and axial loading conditions. His desire was to assess the behavior of the slab for design purposes. For expediency and simplicity of analysis, a simply supported, 100' span with diaphragms at 25' intervals was assumed. Axial loads were applied at both ends with the intent of representing the arch action. (Modified author abstract)
