DESIGNOFHYDRAULICSTEEL Engineering andDesign STRUCTURES
1. Purpose. This manual prescribes guidance for designing hydraulic steel structures (HSS) by loadand resistance factor design (LRFD) and guidance for fracture control. Allowable stress design (ASD)guidance is provided as an alternative design procedure or for those structure types where LRFD criteria have yet to be developed.
2. Applicability. This manual applies to HQUSACE/OCE elements major subordinate mands projects.
