BS 5400-5 is part of a large series of standards concerning the design and construction of bridges. This part makes recommendations for design of bridges that use a composite construction (e.g. employing concrete slabs acting compositely with structural steelwork), and it covers the use of both materials. It is aimed principally at professional engineers involved in the design of bridges, particularly those working in the context of highway and railway engineering. This standard, which is a revision of the 1979 edition, draws heavily on other parts of the same series, particularly Parts 3, 5 and 10.
