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. ...

Webculvert requires: 1) estimating the peak dis-charge of streamflow which would occur at each stream crossing during the 100-year flood, and then 2) determining the size of culvert which would handle that flow using the Federal Highway Administration (FHWA) culvert capacity nomograph (FHWA, 1965). A summary of selected methods, with example WebChapter V discusses culvert capacity calculations. For culvert load rating, capacity is based on equations and approaches specified in AASHTO policy. This chapter presents both the policy and a straightforward approach for determining culvert capacity to facilitate the load rating calculation. Chapter VI presents the Level 1, Level 2, and Level ...
