UPDATE BS 5950-1: 2000 was implemented in August 2001 and, in response, BCSA and SCI have jointly published a new version (the Third Edition) of the Handbook of Structural Steelwork, commonly known as the “Red Book”. The Red Book is an important handbook for steel designers, giving practical design guidance, worked examples, section properties and member capacities in tabular form for use in design. It includes all common steel sections. The first edition of the Red Book was published in 1990, and the second edition in 1991. However, the recent major amendment to BS 5950-1:2000 – Structural use of steelwork in building. Code of practice for design. Rolled and welded sections has necessitated this new third edition of the handbook. The amendment to BS 5950-1 contains some significant technical changes to the rules for steelwork design; these changes have, in turn, been translated into modifications to the member capacities and resistances tabulated in the Red Book. In some instances it has also been necessary to modify the table formats to suit the new design standard. However, designers will find the familiar look and feel of the publication reassuring, and usability has been increased wherever possible. The primary changes in the handbook comprise: • A new section giving practical design guidance to the new standard, • New worked examples to demonstrate the use of the member capacity tables, • Significant changes in the web bearing and buckling tables, • Significant changes in the tables for members subject to axial load and bending, • Increased compression resistance of slender sections, based on the effective area approach of BS 5950-1: 2000 - this has, in particular, improved the resistance of slender UB sections subject to compression, • Section properties tables now include cold-formed hollow sections, parallel flange channels, ASB (asymmetric beams) and deep universal beams. The Red Book has been drafted and published jointly by SCI and BCSA, and constitutes a compressed version of the majority of the information included in the Blue Book (Sixth Edition). The Red Book retains its A5 format and the Blue Book, with its slightly wider scope and detail, remains at A4 size. The Blue Book is already available from BCSA or SCI; the Red Book will be available in the near future (January 2002) for £35.00 (UK sales - with 25% reduction for members of SCI and BCSA). Both Red and Blue Books are part of a range of joint products and services aimed at easing the transition from the 1990 version of the standard to the new 2000 amendment. This range also includes other design aids, currently under development or already complete, such as: • The Green Book (simple connections) - being updated. • In-plane stability of portal frames – new. • Commentary to BS 5950-1: 2000 – new • CD - Electronic guide to BS 5950-1 Amendments – new. • Seminars and Courses. New Steel Construction Vol. 9, issue 2, 2001 was devoted to the BS 5950-1: 2000 Amendment and designers may find it helpful to refer to this.

UPDATE

BS 5950-1: 2000 was implemented in August 2001 and, inresponse, BCSA and SCI have jointly published a new version(the Third Edition) of the Handbook of Structural Steelwork,commonly known as the “Red Book”.The Red Book is an important handbook for steel designers,giving practical design guidance, worked examples, sectionproperties and member capacities in tabular form for use indesign. It includes all common steel sections.The first edition of the Red Book was published in 1990, andthe second edition in 1991. However, the recent majoramendment toBS 5950-1:2000 – Structural use of steelwork in building.Code of practice for design. Rolled and welded sections hasnecessitated this new third edition of the handbook.The amendment to BS 5950-1 contains some significanttechnical changes to the rules for steelwork design; thesechanges have, in turn, been translated into modifications tothe member capacities and resistances tabulated in the RedBook.

standard,• New worked examples to demonstrate the use of the

member capacity tables,• Significant changes in the web bearing and buckling

tables,• Significant changes in the tables for members subject to

axial load and bending,• Increased compression resistance of slender sections,

based on the effective area approach of BS 5950-1: 2000 -this has, in particular, improved the resistance of slenderUB sections subject to compression,

• Section properties tables now include cold-formed hollowsections, parallel flange channels, ASB (asymmetricbeams) and deep universal beams.
