Crucial for durability. Under standard exposure conditions, maximum surface crack widths are generally restricted to 0.25 mm for reinforced concrete, and tighter thresholds apply to prestressed elements to prevent moisture ingress and reinforcement corrosion.
For decades, the British Standard BS 5400 has been the definitive code of practice for the design and construction of steel, concrete, and composite bridges. It has set the technical benchmark for countless highway, railway, and pedestrian bridges across the UK and beyond. Although the standard has now been officially superseded by the Structural Eurocodes, its principles remain highly relevant. BS 5400 continues to serve as a foundation for the assessment of existing structures and is still widely used in many countries for new designs.
