Most structural engineers will have been familiar with CP111 Structural recommendations for loadbearing walls, first published in 1948, revised in 1964, and metricated in 1970. The Code was amended from time to time but was lacking in guidance in several important areas, e.g. the lateral strength of walls and accidental loading. It contained a very short section on reinforced brickwork walls which was not sufficient to enable the material to be used in an economical way. The workmanship, nonstructural design, and some materials aspects of masonry, were dealt with in CP121 Code of practice for walling: Part l: Brick and block masonry, published in 1951 and revised in 1973.

BS 5268 is a compendium of Codes covering the structural use of timber. It brings together design stresses, design methods, and some general guidance on the structural use of timber. It covers the major structural uses of timber, particularly in buildings, and can be used as the basis for design of all timber structural members such as floor and ceiling joists, wall panels, roofs, trussed rafters, and fabricated structural components, such as glued laminated structures and plybox beams. It also covers related information for design against fire and protection against fungal decay and insect attack. BS 5268 is being published in seven Parts: J.G. Sunley
The August 1985 issue contained the statement by the then Secretary of State for the Environment, Mr Patrick Jenkin, that he had laid two sets of building regulations before Parliament. The Building Regulations 1985 supersede The Building Regulations 1976 on 11 November 1985. Because the technical requirements have mostly been recast in a functional form, the new regulations are 25 pages long compared with the present 306. The new regulations will be supported by approved documents issued by the Secretary of State which give practical guidance on how to comply with the requirements. The approved documents refer to British Standards, and it should be a simpler matter to update the approved documents as and when appropriate than to change the references to deemed-to-satisfy documents under the present regulations. In the case of means of escape in case of fire there is no approved document because the mandatory rules for means of escape in case of fire, published by HMSO in July 1985, apply. There is also a Manual to the Building Regulations which contain the regulations, explains the new systems of control, and provides a link between the technical requirements and the approved documents.
