Comdek analyses deep (SD225 and CF210) and shallow (CF46, CF51, CF60, CF80 and CF100) decks in composite floor construction under a wide range of loading configurations. Design principles are in accordance with the appropriate parts of BS 5950 : Part 4 (1994), Part 6 (1995), Part 8 (1991) For design to the Eurocodes, the design principles are in accordance with ENV 1994-1-1 and ENV 1994-1-2:Eurocode 4, with input of partial factors depending on country of use. The design checks performed by the program cover the construction stage, the normal design stage and fire. The slab may be propped or unpropped during construction and may also span over one or more permanent or temporary supports. In the double span case, the spans may be equal or unequal. At the normal design stage, however, the slab is always assumed to be simply supported between permanent supports. The slab is assumed to span only in the direction of spanning of the decking i.e. two-way spanning floors are not covered.
