P325 Introduction to Steelwork Design to BS 5950 1 2000. Discuss me,The Steel Construction Institute, The Steel Construction Institute develops and promotes the effective use of steel in construction. It is an independent membership based organisation. SCI s research and development activities cover many aspects of steel construction including multi. storey construction industrial buildings light steel framing systems and modular construction. development of design guidance on the use of stainless steel fire engineering bridge and civil. engineering offshore engineering environmental studies value engineering and development of. structural analysis systems and information technology. Membership is open to all organisations and individuals that are concerned with the use of steel in. construction Members include designers contractors suppliers fabricators academics and. government departments in the United Kingdom elsewhere in Europe and in countries around the. world The SCI is financed by subscriptions from its members revenue from research contracts. and consultancy services publication sales and course fees. The benefits of corporate membership include access to an independent specialist advisory service. and free issue of SCI publications as soon as they are produced A Membership Information Pack. is available on request from the Membership Manager.

P325 Introduction to Steelwork Design to BS 5950 1 2000. Discuss me, This publication replaces an earlier SCI publication P069 that provided guidance on the. first issue of the design code for steelwork in buildings BS 5950 1 1985 A revised. design code BS 5950 1 2000 which incorporated significant technical revisions came. into effect in 2001 and this led to the need to update that earlier guidance. The material in the present publication has been updated to the latest issue of BS 5950 1. and is presented in 15 principal Sections Guidance is offered on all the main technical. subjects in the Code Further guidance on the application of the Code can be found in a. second SCI publication Steelwork design guide to BS 5950 1 2000 Volume 2 Worked. examples P326, The present publication has been prepared by Mr Andrew Way of The Steel Construction. Institute and incorporates additional lecture material produced by the late Mr Paul Salter. Paul was a well respected colleague who made invaluable contributions to the. development of the publication and SCI wishes to express its gratitude for his input. Further advice and guidance was received during the drafting from Mr Abdul Malik and. Mr Charles King both of The Steel Construction Institute. The preparation of this publication was funded by Corus plc and their support is. gratefully acknowledged, This material is copyright all rights reserved Use of this document is subject to the terms and conditions of the Steelbiz Licence Agreement.

1 1 Introduction, BS 5950 1 2000 1 supersedes BS 5950 1 1990 which is now withdrawn. The new Standard includes technical changes from the previous Standard but. it does not constitute a full revision, The new Standard takes account of a number of new related standards. adopting European or International standards for materials and processes plus. revisions to standards for loading It also reflects the transfer of the design of. cold formed structural hollow sections from BS 5950 5 to BS 5950 1 2000. The clauses that have been updated technically include those for sway. stability resistance to brittle fracture local buckling lateral torsional. buckling shear resistance stiffeners members subject to combined axial force. and bending moment joints connections and testing Descriptions of the. major changes are given in SCI publication P304 2 The reason for many of. the changes to the recommendations is one of structural safety However. where possible some adjustments based on improved knowledge have also. been made to the recommendations to offset potential reductions in economy.

BS 5950 1 is a Standard combining codes of practice covering the design. construction and fire protection of steel structures and specifications for. materials workmanship and erection It comprises the following parts. Part 1 Code of practice for design Rolled and welded sections. 14 4 Connection properties 146 14 5 Frame classification 146 P325 Introduction to Steelwork Design to BS 5950 1 2000 Discuss me
