This Part of this British Standard supersedes CP 117 : Part 2 and augments the provisions of BS 5400 Parts 3, 4 and 10 for structural steel and reinforced or prestressed concrete when components of these materials are so interconnected that they act compositely.
It gives recommendations for rolled or fabricated steel sections, cased or uncased, and for filler beam systems.
Consideration is given to simply supported and continuous composite beams, composite columns and to the special problems of composite box beams. The recommendations for the concrete element cover normal and lightweight aggregate, cast in situ and precast concrete. Prestressing and the use of permanent formwork designed to act compositely with in situ concrete are also covered.
