Purpose. This manual prescribes guidance for designing new hydraulic steel structures (HSS) by Load and Resistance Factor DESIGN (LRFD). This guidance is not intended for use in designing repairs to existing HSS. Allowable Stress DESIGN (ASD) guidance is provided for those structure types where LRFD criteria have yet to be developed.

2 2. Applicability. This manual applies to HQUSACE elements, major subordinate commands, districts, laboratories, and field operating activities having responsibility for DESIGN of civil works projects. 3. Distribution Statement. Approved for public release; distribution is unlimited. 4. References. References are listed in Appendix B.
