About this file

This document is a Bridge Rating Summary and Load Rating Report for a bridge replacement project. The report provides a detailed analysis and load rating calculations for a new steel girder bridge with a timber deck, designated as the Replacement - Bog Dam 4_15-7.9_0922 bridge.

The key details include:

  • The bridge has a span length of 39.17 feet and utilizes a W24x76 steel girder superstructure.
  • The load rating was performed using the Load and Resistance Factor Rating (LRFR) method for various standard and legal vehicles, including the HL-93 design truck, Type 3, Type 3S2, Type 3-3, and various single-unit trucks.
  • The controlling rating factors range from 1.05 to 2.59, with the NRL (Notional Rating Load) truck having a rating factor of 1.37 and a safe load capacity of 54 tons.
  • The report includes detailed calculations and analysis for dead loads, live loads, stresses, resistance factors, and other engineering parameters.
