Load rating of prestressed concrete girder bridges: Comparative analysis of load factor rating and load and resistance factor rating
BJ Rogers, DV Jáuregui - Transportation research record, 2005 - journals.sagepub.com
In light of the adoption of the load and resistance factor design (LRFD) philosophy by the
AASHTO Subcommittee on Bridges and Structures, research efforts are under way to
facilitate the transition from load factor rating (LFR) to load and resistance factor rating
(LRFR) in New Mexico. Five prestressed concrete girder bridges, courtesy of the New
Mexico bridge inventory, were rated with the BRASS-GIRDER and BRASS-GIRDER (LRFD)
structural software. The objectives for this study were to evaluate and verify the BRASS …

Load Rating of Prestressed Concrete Girder Bridges: A Comparative Analysis of LFR and LRF
BJ Rogers, DV Jauregui - 2005 - trid.trb.org
With the intention of supporting the Federal Highway Administration's implementation of
Load and Resistance Factor Design (LRFD), research efforts were made to facilitate the
transition from Load Factor Rating (LFR) to Load and Resistance Factor Rating (LRFR) in
the state of New Mexico. Five prestressed concrete girder bridges, courtesy of the NM bridge
inventory, were rated using the BRASS-GIRDER and BRASS-GIRDER (LRFD) software.
Research objectives include 1.) the evaluation of the BRASS software prior to full …
