Structural steel design to BS 5950, part 1

BS 5950, the design code for structural steel has been greatly revised. Joannides and Weller introduce the new code and provide the necessary information for design engineers to implement the code when designing steel structures in the UK.

This timely book introduces design engineers to the use of BS5950 and gives the necessary information for them to be able to carry out satisfactory design for steel structures covered in the standard. This includes some guidance on loading and where further information may be obtained. The book discusses various clauses in BS5950 in the light of the basic theory and gives the necessary background information to ensure a good understanding of the document. Worked examples are supplied.
