Let’s extract a real example from a typical annotated PDF of Part 4:
Given: Slab depth ( h = 600 ) mm, effective depth ( d = 540 ) mm, ( b = 1000 ) mm, ( f_cu = 40 ) N/mm², ( A_s = 1960 ) mm²/m (5T25 @ 200mm c/c). Shear force ( V_Ed = 350 ) kN/m at support.
Solution per Clause 5.3.4:
This step-by-step logic is impossible to replicate without a reliable concrete bridge design to bs 5400 pdf.
BS 5400: Part 4 adopts the rectangular stress block (simplified from the parabolic-rectangular shape). For a section in bending: concrete bridge design to bs 5400 pdf
The design moment resistance (M_Rd) for singly reinforced section is:
[ M_Rd = 0.156 , f_cu , b , d^2 ]
Where 0.156 is the limiting value for a singly reinforced section (similar to Eurocode’s 0.167 but based on cube strength).

Despite its withdrawal, BS 5400 concrete bridge design principles remain embedded in:
For the young engineer, mastering BS 5400 via authentic PDFs provides the historical context needed to understand why modern codes evolved. For the experienced practitioner, it remains an essential tool for asset management. This step-by-step logic is impossible to replicate without
