Please refer to span parameters on page 12. The figures in brackets are mesh size references.* In accordance with BS EN 1994-1-1 Clause 9.8.1 (2) - the minimum cross-sectional area of anti-crack reinforcement above the ribs should not be lessthan 0.2% for unpropped construction. In order to maximise the FIRE LIMIT STATE spans, increased mesh sizing is required as specified in the above table.

End anchorage for bar reinforcement. All cases require properly anchored L-bars at the supports, except for those marked .

These cases may have straight bars, with an anchorage length of 70 mm from the edge of the support.See Design Notes on page 00 for further information. One bar is placed in each profile trough, the cover to deck soffit is assumed at 70 mm.

Please refer to span parameters on page 12.

End anchorage for bar reinforcement. All cases require properly anchored L-bars at the supports, except for those marked .

These cases may have straight bars, with an anchorage length of 70 mm from the edge of the support.See Design Notes on page 00 for further information. One bar is placed in each profile trough, the cover to deck soffit is assumed at 70 mm.

Parameters assumed for quickreference span tables

MeshRefer to product specific design notes.

SpansMeasured centre to centre of supports.

DeckStandard deck material specification.

Bearing widthThe width of the support is assumed to be

150 mm for shallow decks.

Prop widthAssumed to be 100 mm.

DeflectionConstruction stage L/130 or 30 mm (ponding

has been taken into account).

DeflectionComposite stage L/350.

Concrete gradeThe concrete is assumed to be Grade 35 with a

maximum aggregate size of 20 mm. The wet

weight of concrete is taken to be normal weight

2400 kg/m3 and lightweight 1900 kg/m3. The

modular ratio is 10 for normal weight and 15 for

lightweight concrete.

Construction load1.5 kN/m2 construction load is taken into

account, in accordance with BS 5950:Part 4.

No allowance is made for heaping of concrete

during the casting operation. See product

specific design notes.Applied loadThe applied load stated in the tables covers

allowable unfactored imposed live load.

Partition loads, finishes, ceilings and services are

not included. However the dead load of the slab

itself has already been taken into account and

need not be considered as part of the applied

load.

Simplified fire design methodThe fire recommendations in the tables are

based on the simplified design method.

Fire engineering methodThe fire engineering (FE) method may be used

to calculate the additional reinforcement

needed for fire, load and span conditionsbeyond the scope of these tables. The FE

method of design is provided in the design CD.

Fire insulationThe minimum slab thickness indicated in each

table, for each fire rating satisfies the fire

insulation requirements of BS 5950:Part 8.

Span/depth ratioSlab span to depth ratio is limited to 30 for

lightweight concrete and 35 for normal weight

concrete.
