scope:
The methodology is presented in a general format utilizing load and resistance factors. This procedure allows for combining probability theory, statistical data and engineering judgment into a rational decision making tool. In particular, the procedure allows the engineer to use site specific information in a consistent manner to improve, if necessary, his judgment on the safe rating level for a particular bridge. In addition, the format incorporates existing methodology for considering local laws and regulations and methods of calculation.
Purpose
These proposed guidelines establish a methodology for rating existing bridges.
