Load Rating of Aravaipa Bridge
Structural Design Pinal County, Arizona
Structural Grace, Inc. conducted a bridge load rating analysis for the Aravaipa Road Bridge over Aravaipa Creek in eastern Pinal County. The team determined the loading, member section properties, and capacities for the proprietary pinned truss (aka a Bailey Bridge), and produced a final Bridge Load Rating Report documenting the results of the analysis and recommending a safe posting load in order to satisfy the local Firewise Program requirements. The load rating for the superstructure was per LRFR methodology. A field review was also conducted to confirm site conditions and obtain additional pertinent information. This 260’ simple span bridge has over 4,000 members that were analyzed in a 3-D model with eight different moving live load vehicles.
