Masonry Codes CP 111 and BS 5628-Differences, and Assessment of Draft BS 5628
The first part of this paper indicates the principal differences between BS 5628: Part 1: 1978: The structural use of masonry and CP 111: 1970: Structural recommendations for loadbearing walls, and outlines the reasons behind the changes. They are essentially a combination of experience of the performance of buildings in service and new research data. The second part describes the assessment made during the final stage of drafting to ensure that the document was operationally satisfactory and that it provided suitably safe designs by comparison with existing practice.
