The objective of the calibration of codes based on a LRFD format is to provide optimal partial factors for the design of a type of structure, which lead to designs as close as possible to the code objective.
"Prior to the LRFD Bridge Specification revisions, engineers were limited in their designs to only include reinforcing steel up to 75 ksi for bridge structures," notes Russo.

Kim [9] proposed new load combinations for the load and resistance factor design (LRFD) to design typical IABs, by developing the nominal IAB response prediction models and establishing IAB's response statistics using Monte Carlo simulation.
Aramid fiber-reinforced (ARFP) bars may successfully replace conventional steel and prestressing strand, providing sufficient strength per AASHT0 LRFD Bridge Design Specifications (2010), and considerable deformability when compared to the conventional system, say Shobeir Pirayeh Gar, Stefan Hurlebaus, John Mander, Zachry Department of Civil Engineering, Texas A&M University, and Monique Head, Morgan State University, Baltimore, in their paper, Comparative Experimental Performance of Bridge Deck Slabs with APRP and Steel Prestressed Precast Panels.
Areas covered include reliability-based design, LRFD concepts, in situ soil testing, geotechnical design of combined spread footing, design of drilled shafts, and stability analysis and design of slopes.
