BS 5268 V EC5 SPAN TABLES - MISINTERPRETATION OF CLG GUIDANCE

摘要

TRADA Technology has been contacted by builders advised by Building Controlthat they might need to rebuild roofs and other structures if built using the BS 5268 version of its Span tables for solid timber members in dwellings, instead of the Eurocode 5 (EC5) version, as the result of a misinterpretation of guidance issued by the Department of Communities and Local Government (CLG). CLG contacted local authorities, Building Control, approved inspectors and other interested bodies on 29 January 2012 about the introduction of the Eurocodes, and the associated withdrawal by British Standards Institution (BSI), in March that year, of conflicting BS design standards. Some of these design standards, including BS 5268, are referenced in the Building Regulations Approved Documents, particularly Approved Document A (Structure).
