Limits maximum compressive and tensile stresses in both the concrete and reinforcement under nominal service loads. 3. Bridge Loading and Combinations (BS 5400 Part 2)
Hope this helps someone out! Let me know in the comments if you have other recommended resources for bridge design.
The UK’s Highways Agency (now National Highways) published and BA 44/96 – "The Design of Concrete Bridges" – which are interpretive guides to BS 5400 Part 4. These are freely available as PDFs from the Standards for Highways website. They distil the essential clauses into flowcharts, tables, and worked examples.
Ultimate Limit State (ULS): Ensuring the bridge does not collapse under extreme loads. concrete bridge design to bs 5400 pdf
SLS ensures the bridge functions adequately under normal day-to-day conditions without excessive distress. Key criteria include:
A critical phase of the design workflow is establishing the design loads. BS 5400 Part 2 classifies loads into permanent, transient, and environmental types. Permanent Loads
ULS focuses on the structural strength and safety against collapse, overturning, or buckling. The design load effects must not exceed the design strength of the materials.

The specific requirements for the method of analysis are outlined in BS 5400 Part 4. Bridge engineers generally utilize linear elastic methods of analysis (e.g., grillage analysis, finite element modeling, or space frame models) to determine internal forces and deformations.
