This software analyses CMF MetFloor composite floor slabs in buildings subject to a wide range of loading configurations. Design can be made either to BS 5950 or to Eurocodes.
The following load configurations are supported:
The software covers non-composite design of the deck at the construction stage and composite design of the slab at the normal service stage. The software allows fire resistance design and serviceability limit state checks include deflection and vibration.
The deck may be single spanning or continuous over several bays. Multi spans must be equal. Double spans may be unequal. The deck may be propped or unpropped during construction. Its resistance is derived from tests, which are also the justification for the elasto-plastic analysis adopted by the software. Serviceability checks are based on elastic analysis.
For normal design, the slab is always assumed to be single spanning at the composite stage regardless of the assumptions made about the deck at the construction stage. The slab is assumed to span ONLY in the direction of span of the profiled decking. For assessing the bending resistance of the composite slab, the decking (in combination with any bar reinforcement provided) is treated as tension reinforcement. Any mesh provided is treated as anti-crack reinforcement and checked for code compliance dependent on the form of construction.
The total self-weight of the slab is automatically calculated by the program from the floor layout and support details.
Design for the fire limit state is based on temperature profiles at given fire resistance periods and residual material strengths at these temperatures.
The software interface allows the user to include several deck/slab designs calculations in a single file.
Design to British Standards or to Eurocodes is possible. Selection is made by clicking on the relevant button on the toolbar.
