Lrfd method example
WebLRFD has been used increasingly and become mandatory for design of all bridge projects funded by FHWA. Compared to the ASD method, LRFD can achieve a compatible reliability between the bridge superstructure and substructure. The uncertainty of load and resistance are quantified separately and reasonably incorporated into the design process.
