Phạm vi áp dụng / Scope of standard

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.
