BS 5400
BS 5400 was a British Standard code of practice for the design and construction of steel, concrete and composite bridges. It was applicable to highway, railway and pedestrian bridges. It has now been replaced by the European standard, BS EN 1991-2_2003[1] and other Eurocodes for the design of steel and concrete structures.
The standard specifies the requirements and the code of practice[2][3] on design of steel,[2] concrete (reinforced, prestressed or composite)[3] and composite bridges that use steel sections (rolled or fabricated, cased or uncased)[4] as well as the materials and workmanship in bridge erection.
The standard also includes the specification and calculation of standard bridge loads, the application of the limit state principles,[5] analysis, and fatigue load calculation[6] and the reservoir method for fatigue load cycle counting.[6]
The standard also encompasses the structural design of bridge foundations[5] as well as the design and requirements of bridge bearings for both ordinary and moving bridges.[7][8]
In 2010, BS 5400 was superseded by the Structural Eurocodes for the design of new bridges. However, BS 5400 still serves as the foundation for assessment standards concerning existing highway and railway structures. Some of the prescriptive clauses from the old code have been reformulated to align with the principles of the Eurocodes and are presented as advisory material within British Standard Published Documents. These documents serve as non-contradictory complementary information (NCCI) to the Eurocodes, providing means of compliance with Eurocode requirements, often utilizing closed-form solutions familiar to engineers experienced in the application of BS5400.
