The Structural Engineer, Volume 60, Issue 9, 1982
CP3: Chapter V: Part 2: 1972 A letter from Mr D. J, Ascough covered a number of points that have been aired in previous issues. In June 1982 this column set out three of the examples he presented to show that it is possible to build an unsafe building and comply with traditional Codes of Practice. His fourth example was set out thus: Although by no means as serious as the previous examples, the discrepancies in CP 3: ChV: 1972 deserve wider publicity. Depending on whether they are obtained from Table 10 or are taken as the aggregate of Cpe from Table 7, the wind forces used for the design of a frame can vary by 20 % without extrapolation, and more if Table 7 values are extrapolated. This is an unsatisfactory state of affairs! Are designs based on Table 7 unsafe, or those on Table 10 ultraconservative? Verulam

Following general discussions in 1981 on changes in the Building Regulations (CMND 8179; The future of building control in England and Wales) the Department of the Environment last May invited comments on two consultative documents: The FORM of future Regulations; and their CONTENT. On behalf of the Council the President has authorised that the following observations be sent to the Department as reflecting views of the Institution. The comments have been drawn up by the Working Party appointed by the Council under the Chairmanship of Mr R. J. M. Sutherland (Vice-president). The Department has proposed that the Regulations themselves should be confined to broad functional requirements purely expressive of their tasks.
