A procedure for carrying out the detailed design of flat slabs is shown in Table 1 below. This assumes that the slab thickness has previously been determined during conceptual design. Concept designs prepared assuming detailed design would be to BS 8110 may be continued through to detailed design using Eurocode 2.
More detailed advice on determining design life, loading, material properties, methods of analysis, minimum concrete cover for durability and bond, and control of crack widths can be found in Chapter 2 of How to Design Concrete Structures using Eurocode 2.
