Overview of AASHTOWare's Bridge products, including Bridge Management, Bridge Design, and Bridge Rating.

The main objective of this study was to evaluate and improve ODOT’s current load rating procedures for corrugated metal culvert.

The Bridge Advisory (BA) is intended to convey information to MDOT, local agencies, and contractors working for these agencies. The intent of the advisories is to provide guidance and share information on bridge safety, bridge inspection, bridge management, and bridge load rating issues.

AASHTO has nearly 100 tutorials to help users with conducting load ratings for various types of structures. Tutorials also illustrate how to use new load rating software components such as gusset plate analysis, 3D modeling, and curved girder analysis.

This tutorial is a general guide for modeling a camelback bridge in AASHTOWare Bridge Rating. The tutorial methodology relies on a sample MDOT standard plan bridge that has a 60-ft reinforced concrete girder with a 22-ft roadway, but it should be adapted accordingly for any modifications to the standard plan and for the specific rebar present in the bridge.

These spreadsheets aid a qualified engineer, using sound engineering judgment and familiarity wtih the analysis, in inputting values and completing the bridge load rating analysis of a corrugated metal pipe culvert structure.
