Are Our Code Provisions for Slabs Safe?

A number of inconsistencies in the approaches given in British Codes for the design of reinforced concrete slabs are discussed. These are cases where a more rigorous design leads to a requirement for more reinforcement than do simplified methods. Since experience suggests that the simplified methods are adequate, a review of the bases of slab design seems necessary. Various aspects of the behaviour of slab systems are discussed including the nature of loading and membraneffects. It is suggested that the more rigorous design methods are indeed overconservative, and a change in the design load patterns is proposed. A.W. Beeby
