BS 5950

BS 5950 is a British Standard for structural steelwork in buildings. It provides recommendations and guidance for the design, fabrication, and erection of steel structures. The standard is divided into several parts, each covering specific aspects of steel design. Key parts include:

• BS 5950-1: Code of practice for design in simple and continuous construction: Hot rolled sections. This part covers the design of steel structures using hot-rolled sections, encompassing simple and continuous construction methods. It details requirements for member resistance, stability, and connection design.

• BS 5950-2: Specification for materials, fabrication and erection. This part addresses the material requirements for steel used in construction, as well as specifications for fabrication and erection processes. It covers topics such as welding, bolting, and surface protection.

• BS 5950-3: Code of practice for design of simple and continuous composite beams. This part focuses on the design of composite steel and concrete beams.

• BS 5950-4: Code of practice for design of composite slabs with profiled steel sheeting. It details the design procedures for composite slabs using profiled steel sheeting.

• BS 5950-5: Code of practice for design of cold-formed sections. This part covers the design of steel structures using cold-formed sections.

• BS 5950-6: Design in composite construction. This part includes sections for composite columns and frames.

• BS 5950-7: Code of practice for design of simple structures. This part simplifies design for certain relatively simple steel structures.

• BS 5950-8: Fire resistant design. Addresses the design of steel structures to resist fire.

BS 5950 has largely been superseded by the Eurocodes, specifically the EN 1993 series (Eurocode 3: Design of steel structures). While still used in some instances, particularly in projects where it was specified at their outset, Eurocode 3 is now the prevailing standard for steel structure design in the UK and Europe.
