tailieunhanh - Part 1: Code of practice for design — Rolled and welded sections

This part of BS 5950 supersedes BS 5950-1:1990, which is withdrawn. A period of three months is being allowed for users to convert to the new standard. This edition introduces technical changes based on a review of the standard, but it does not constitute a full revision. This new edition has been prepared following the issue 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 cold formed structural hollow sections from BS 5950-5 to BS 5950-1 | BRITISH STANDARD BS 5950-1 2000 Incorporating Corrigendum No. 1 Structural use of steelwork in building Part 1 Code of practice for design Rolled and welded sections ICS NO COPYING WITHOUT BSI PERMISSION EXCEPT AS PERMITTED BY COPYRIGHT LAW III BS 5950-1 2000 Committees responsible for this British Standard The preparation of this British Standard was entrusted by Technical Committee B 525 Building and civil engineering structures to Subcommittee B 525 31 Structural use of steel upon which the following bodies were represented British Constructional Steelwork Association Building Research Establishment Ltd Cold Rolled Sections Association Confederation of British Metalforming DETR Construction Directorate DETR Highways Agency Health and Safety Executive Institution of Civil Engineers Institution of Structural Engineers Steel Construction Institute UK Steel Association Welding Institute This British Standard having been prepared under the direction of the Civil Engineering and Building Structures Standards Policy Committee was published under the authority of the Standards Committee on 15 May 2001.
