Unformatted text preview: slab and too little somewhere else, the resulting slab behavior will probably still be satisfactory. The total amount of reinforcement in a slab seems more important than its exact placement. Designers may design slabs on the basis of numerical solutions, yield-line analysis or other theoretical methods provided that it can be clearly demonstrated that they have met all the necessary safety and service ability criteria required by the ACI code. Although it has been the practice of designers for many years to use approximate analyses for design and to use average moments rather than maximum ones two-way slabs so designed have proved to be very satisfactory under service loads. Furthermore, they have been proved to have appreciable overload capacity....
