Abstract:
In the UK, BS8007 has provided the basis for the design for early-age thermal cracking. This is to be replaced by EN1992-3 and in conjunction with the replacement of the general design code, BS8110 by EN1992-1-1 this has led to significant changes in some aspects of design. BS8007 was supported by CIRIA 91 which provided background to the design method and data for use in the design process. This has been updated and replaced by CIRIA C660 which brings the design into line with the Euro-codes and provides current information required to support the design process. The significant changes are described and their implications are discussed. AS3600 and AS3735 crack control provisions are based on the principles of BS 8007 and may need revision to take account of the changes outlined herein.
