Covers design for concrete, steel, aluminum, and wood structures.
The serves as a foundational document for understanding the transition to modern, reliability-based bridge design. While newer versions are currently mandatory for new projects, the 5th edition remains relevant for evaluating existing structures and understanding the evolution of the LRFD design philosophy.
: In structural failure investigations, forensic analysts use the code active during the bridge’s design phase to determine if compliance issues contributed to the defect.
