Culvert load capacity chart
Web4.2.4 Rigid Culvert Behavior The load carrying capacity of rigid culverts is essentially provided by the structural strength of the pipe itself and little benefit from the surrounding earth is required. When vertical loads are applied to a rigid pipe, zones of tension and compression are created as illustrated in Figure 4-7. ... WebThere is some common terminology that is used in culvert hydraulics that can best be presented by referring to Figure 1. The culvert itself consists of an entrance, an outlet, and a culvert barrel. Common culvert shapes include …

WebThese loads were then used to calculate shears and moments in the culverts slab. An equivalent uniform load that produced the same maximum shear or moment as did the AASHTO trucks was then computed. These equivalent loads were then plotted versus soil depth to develop design equations. Based on the results, the final design
