The design moment resistance (M_Rd) for singly reinforced section is:
Combination 1 + Temperature effects (+ secondary effects).
Unlike Eurocodes, BS 5400 uses that vary depending on the load type and combination, rather than the Eurocode’s ψ factors for accompanying variable actions. concrete bridge design to bs 5400 pdf
The self-weight of the structural concrete elements.
BS 5400 operates on a dual limit state philosophy to ensure structural safety, longevity, and structural functionality over a typical . Ultimate Limit State (ULS) The design moment resistance (M_Rd) for singly reinforced
The standard classifies material strengths to establish reliable resistance metrics. Concrete Strength and Modulus

Comprehensive Guide to Concrete Bridge Design to BS 5400 BS 5400 is the classic British Standard code of practice for the design and construction of steel, concrete, and composite bridges. While the industry has transitioned to the Eurocodes (BS EN 1991 to BS EN 1994), BS 5400 remains highly relevant for evaluating legacy infrastructure, maintaining existing structures, and executing projects in regions that still utilize British Standards.

ULS focuses on the safety of the structure against total collapse or catastrophic failure.
The central innovation of BS 5400 was its implementation of , moving away from older "working stress" methods. This approach ensures a structure remains fit for its intended use through two primary criteria:
