Unpropped - Quick Reference Load Span Table Notes Double Span in Construction - Simple Span in Service

The purpose of these tables is for rapid conceptual design only. A full design analysis using the ComFlor software (and other ‘whole system’ software) is required to verify all design parameters are met.

Double Span in Construction

Sheets are continuous over permanent supports

End span (use double span data)

Internal span

End span (use double span data)

Spans shown in this table are ‘centre to centre’ of 150mm wide (top flange) beams as is typical in unpropped continuous sheet construction. Wider beams will result in longer spans. To this end these tables can be considered conservative in most applications.

Spans listed are in 50mm increments with intermediate values at 25mm. Generally for double span construction, strength of the sheet over the support will govern the design.

Even if the ComFlor sheets are continuous over a permanent support in construction, the slab will act as a simple span in service unless full continuity reinforcement is placed over the permanent supports. 25MPa (cylinder strength) concrete used.

95% strength in construction

The green zone is the ‘safe’ zone within which the ComFlor is not unduly taxed structurally during construction.

98% strength in construction

The orange zone can be considered the ‘working’ zone where most efficient designs will occur. Concrete pour sequencing is important within the orange zone to minimise ponding and result in flatter concrete surface.

100% strength in construction

The red zone should never be used.

Permanent support

Sheets are continuous over permanent supports

Double (or end) span

Double (or end) span

General Apart from the 0.75mm data, these tables have been derived from version 8.3 of the ComFlor design software. The 0.75mm data has been derived manually based as closely as possible to those parameters used in ComFlor. Outputs from future versions of ComFlor may differ slightly from those in these tables, therefore is important to always verify a design using the latest software.

The construction deflection column to the right of the tables indicates the resultant deflection at the end of each of the colour bands.

Ultimately it is the ’clear span’ that dictates the design. As the top flange width increases with larger beam selection, the possible beam centres increase. Specific design using the ComFlor software is required.

5mm, 15mm, 22mm indicate the underside deflection to expect (inclusive of concrete ponding midspan) during construction. The line to the right thus 5mm indicates the span applicable to that deflection figure. As a guide: 5mm – Practically flat appearance to the underside 15mm – 15mm underside deflection has generally proven to be a good compromise between visual appeal and functional construction spans.

22mm – A good ‘working’ maximum where underside appearance is not important, but maximum construction spans are desired.

25mm – Generally the absolute maximum underside deflection advised unless the visual appearance is of no relevance.

Category Reference from AS/NZS 1170.1:2002, table 3.1

Note - Point loads have not been considered for these quick reference tables. Please use the ComFlor software and/or discuss your needs with a ComFlor representative.

The composite (normal stage or ‘in service’) spans are designed to a 5Hz vibration limit. Studies of existing slabs have shown that this parameter results in a solid feeling slab that does not generally produce unsettling vibration underfoot if the support structure is inherently rigid (ie a concrete block wall). Please note that the slab alone does not necessarily dictate the overall slab ‘system’ vibration characteristics. If the support structure has the potential to be flexible (ie structural steel), the whole floor system should be considered for vibration. Spans can be increased markedly if the vibration criterion is relaxed or not critical to the end use of the slab.

Load/span combinations in these tables achieve a guaranteed 30 minute fire resistance rating (FRR). Greater than 30 minutes is often possible, dependant on the actual imposed load (tables give possible load based on 30 minutes FRR) - use the ComFlor software to determine if the desired FRR can be achieved without additional reinforcing. Use the ‘Simple’ setting first to determine if mesh alone will satisfy the fire condition. ComFlor allows for different mesh sizes to be considered in the ‘Simple’ method - or, using the ‘Fire Design’ method different bar sizes (10 to 32mm) can be placed in the ComFlor troughs in order to improve fire performance.

Quick Reference Load Span Table Notes Single Span in Construction - Simple Span in Service

The purpose of these tables is for rapid conceptual design only. A full design analysis using the ComFlor software (and other ‘whole system’ software) is required to verify all design parameters are met.

Spans listed are in 100mm increments with intermediate values at 50mm. For unpropped single span design, underside deflection during the concrete pour will (generally) govern the effective span. For propped single span design, the resultant vibration and deflection characteristics of the composite slab will (generally) govern the design.

Single span in construction

‘stand alone’ span between two permanent supports

Single span unpropped (can be propped for longer spans)

‘stand alone’ span between two permanent supports

ComFlor sheet

Even if the ComFlor sheets are continuous over a permanent support in construction, the slab will act as a simple span in service unless full continuity reinforcement is placed over the permanent supports. 25MPa (cylinder strength) concrete used.

Permanent support

Sheets DO NOT continue over permanent supports

Construction Stage The colour zones on the table represent the ponded (soffit) deflection to expect during construction.

ComFlor sheet

Temporary line of propping Single Span propped

Single Span unpropped

General Apart from the 0.75mm data, these tables have been derived from version 8.3 of the ComFlor design software. The 0.75mm data has been derived manually based as closely as possible to those parameters used in ComFlor. Outputs from future versions of ComFlor may differ slightly from those in these tables, therefore is important to always verify a design using the latest software.

8

ComFlor

Spans shown in this table are ‘clear span’ plus 100mm to reflect the typical application of the ComFlor sheet in a single span slab - 50mm seating onto the support structure.

15mm deflection

16 to 22mm deflection

over 23mm deflection

5mm, 15mm, 22mm indicate the underside deflection to expect (inclusive of concrete ponding midspan) during construction. The line to the right thus 5mm indicates the span applicable to that deflection figure. As a guide: 5mm – Practically flat appearance to the underside.

15mm – 15mm underside deflection has generally proven to be a good compromise between visual appeal and functional construction spans.

22mm – A good ‘working’ maximum where underside appearance is not important, but maximum construction spans are desired.

25mm – Generally the absolute maximum underside deflection advised unless the visual appearance is of no relevance.

Normal Stage Strength criteria limited to 95% utilisation Total Deflection is limited to the smaller of span/250 or 30mm Serviceability criteria limited to 99% utilisation (of 5Hz)

Propping Please note, when propping is used, the self weight of the slab is applied as a dead load once props are removed and can result in lower load capacity than that of an unpropped slab of the same span. This is because (the self weight of) an unpropped slab ‘loads up’ as it is poured, whereas when propped the self weight is held by the propping initially.

The composite (normal stage or ‘in service’) spans are designed to a 5Hz vibration limit. Studies of existing slabs have shown that this parameter results in a solid feeling slab that does not generally produce unsettling vibration underfoot if the support structure is inherently rigid (ie a concrete block wall). Please note that the slab alone does not necessarily dictate the overall slab ‘system’ vibration characteristics. If the support structure has the potential to be flexible (ie structural steel), the whole floor system should be considered for vibration. Spans can be increased markedly if the vibration criterion is relaxed or not critical to the end use of the slab.

The propping break lines (from 0 to 1, 2 or 3 rows required) occur at 95 % strength utilisation of the ComFlor sheet in construction.

The heavy lines indicate those points at which one or more prop lines are required.

The propping line used must be checked to ensure it has the required capacity to support the construction loads. ComFlor has the capacity to span far enough to impart up to 1500kg per linear metre onto the propping line.

Spans can be further increased by the addition of bottom reinforcing. Up to 600mm (varies) additional span can be achieved to that shown. Bottom reinforcing can be added also to increase the load carrying capacity of any given span/slab thickness combination. Use the ComFlor design software to verify.

A top bearer width of 100mm is used for the temporary propping system. Construction spans can be increased if wider bearers are used.

Load/span combinations in these tables achieve a guaranteed 30 minute fire resistance rating (FRR). Greater than 30 minutes is often possible, dependant on the actual imposed load (tables give possible load based on 30 minutes FRR) - use the ComFlor software to determine if the desired FRR can be achieved without additional reinforcing. Use the ‘Simple’ setting first to determine if mesh alone will satisfy the fire condition. ComFlor allows for different mesh sizes to be considered in the ‘Simple’ method - or, using the ‘Fire Design’ method different bar sizes (10 to 32mm) can be placed in the ComFlor troughs in order to improve fire performance.
