INELASTIC RATING PROCEDURES FOR STEEL BEAM AND GIRDER BRIDGES

The main purpose of this paper is to develop a method of rating existing straight steel beam and girder bridges which makes use of the inelastic reserve capacity inherent in steel bridges. This inelastic capacity stems from the strength and rotational capacity of compact steel sections, the composite action of deck slabs, and the three dimensional action present in bridge structures. A shakedown limit state was selected as the appropriate rating limit. Computer programs and hand computation techniques were developed to obtain the rating factor. An addendum to existing AASHTO provisions was developed and sample rating exercises conducted.
