Whether you are an MSc student writing a dissertation on an existing viaduct, or a chartered engineer conducting an assessment, a legitimate PDF copy of Part 4 remains a tool of trade. Always verify the amendment status, and cross-reference with BD 44/95 for clarity.
Tensile stresses are permitted, but they must not cause visible cracking.
Includes bending, shear, torsion, longitudinal shear, and buckling of compression members. Serviceability Limit State (SLS)

BS 5400 is the classic British Standard code of practice for the design and construction of steel, concrete, and composite bridges. While largely superseded by the Eurocodes (BS EN 1991 to BS EN 1994) for new public projects in the UK and Europe, BS 5400 remains a benchmark standard globally. It is widely utilized in international regions, historical asset management, and structural rehabilitation projects.

No tensile stresses are permitted under nominal loading (fully prestressed). Legacy PDF compilations often bundle these as a
Reinforcement steel must comply with BS 4449: yield strength ( f_y = 460 ) N/mm² (high-yield bars). Partial safety factor for steel in ULS: ( \gamma_m = 1.15 ).
