For information regarding BS 5400 Part 4 (the British Standard for the design of concrete bridges), you can access official documents and comprehensive guides through several professional platforms. Core Standard and Codes BS 5400-4:1990 : This is the primary Code of Practice for the design of concrete bridges
2.3 Durability and Cover (Clause 6)
BS 5400 was pioneering in its rigorous durability requirements. Minimum cover to reinforcement depends on: concrete bridge design to bs 5400 pdf
- BS 5400-2 (1978/2006): Loads and load combinations.
- BS 5400-4 (1984/1990): Design of concrete bridges – materials, analysis, and detailing.

Step 1 – Flexural reinforcement
[
K = M / (b d^2 f_cu) = 320 \times 10^6 / (1000 \times 440^2 \times 40) = 0.041
]
Since K < 0.156 → singly reinforced.
[
z = d [0.5 + \sqrt0.25 – K/0.9] = 440 [0.5 + \sqrt0.25 – 0.041/0.9] = 418 \text mm
]
[
A_s = M / (0.87 f_y z) = 320 \times 10^6 / (0.87 \times 460 \times 418) = 1916 \text mm^2/m

Provide T20 @ 150 mm c/c (2094 mm²/m). For information regarding BS 5400 Part 4 (the
Part 2 (as modified by BD 37/01): The standard used for Highway Bridge loading in the UK. BS 5400-2 (1978/2006): Loads and load combinations
- C40 (40 N/mm²): Minimum for reinforced concrete superstructures.
- C50 (50 N/mm²): Common for prestressed concrete beams.
- C60+ (60 N/mm²): Used for high-performance, durability-critical zones.
4.5 Step 5: Ultimate Flexural Strength (Clause 5.4)
- Use parabolic-rectangular stress block: 0.45 fcu for concrete, εcu = 0.0035.
- Calculate moment capacity Mu, ensure Mu > Mapplied.
Conclusion
The search for "concrete bridge design to BS 5400 pdf" reflects an enduring need for a withdrawn but vital engineering standard. While authentic PDFs are best obtained through institutional or paid BSI access, numerous textbooks, comparison guides, and legacy software tools can help you apply BS 5400 effectively.
Part 2: Specification for Loads – Defines nominal loads and partial safety factors for highway, railway, and footbridges.
