Introduction

FibreFlor Mesh Free Composite Floor System

Benefits of FibreFlor

Cost Savings

Labour cost savings

Up to 20% programme savings

No mesh to purchase, transport or store

Reduction in crane hire costs

Potential concrete volume savings

Easier to Install

No hoisting / lifting or manual handling of mesh

No steel fixing/tying requirements

No spacer requirements

3-Dimensional reinforcement delivered ready mixedin concrete

Easier concrete application (No trip hazards or snagging

from mesh)

Fibre reinforcement always in the correct position

Technical Superiority

Independent testing proves that the FibreFlor system

provides equivalent or superior performance to traditionalwelded wire mesh solutions.

Quality assured concrete reinforcement system.

FibreFlor is proven to reduce plastic shrinkage and

settlement cracking.

Unlike macro-synthetic fibres, the micro-synthetic fibres

in FibreFlor are also proven to mitigate the explosive

spalling tendency of concrete during fires.

The inclusion of steel fibres in FibreFlor provides load

bearing capabilities, increased toughness and long term

crack control.

FibreFlor is a partnership between Corus and Propex

Concrete Systems, the worlds largest supplier of fibre

reinforcement for concrete. FibreFlor uses a combination

of high performance steel fibres and polypropylene

micro-synthetic fibres to provide a three dimensional

fibre reinforced concrete composite slab.

Traditionally composite metal deck construction utilises

mesh fabric reinforcement. This involves the delivery, lifting

and installation of welded wire mesh on to the floor prior tothe pouring of concrete. The time and costs involved make

mesh relatively unpopular with contractors and the mesh

itself is a hindrance to other site operations. Maintaining

the correct mesh height, position, concrete cover and laps

can be difficult during mesh placement and concrete

pouring.

FibreFlor reinforcement is provided within the concrete,

delivered and ready to pump at site. Significantly this can

reduce installation times by up to 20%.

FibreFlor is a certified floor deck system that eliminates the

need for steel wire mesh and is currently available as

FibreFlor CF51, FibreFlor CF60 & FibreFlor CF80.

The benefits of Coruscomposite floor decking

Professional SupportCorus Panels and Profiles maintains a friendly technical

help desk, which is freely available to all Consulting

Engineers and Contractors to assist in Composite flooring

design issues. The technical help desk is available

on 0845 30 88 330.

Quality

To provide the best quality and the most up to date design

information, Corus Panels and Profiles is quality assured to

BS ISO 9001:2000 Quality systems. Corus Panels and

Profiles is an active member of MCRMA (Metal Cladding

and Roll Forming Manufacturers Association), The SCI

(Steel Construction Institute), BCSA (British Constructional

Steelwork Association) and supports the research and

development industry wide.

The widest range of shallow decks

From ComFlor

46 all the way to ComFlor

100 the Corusrange of decks provides the optimum solution for all over

beam applications.

Covering unpropped construction from 2.5 to 4.5 metres

each ComFlor profile offers particular application benefits.

The shallow decks are suitable for conventional composite

construction where the deck is placed onto the top flange

of the steel support beam.

Two deep composite floor decks

ComFlor 210 and ComFlor 225 are both designed to be

used with the Corus Slimdek system, which uses

asymmetric beams. The floor deck lands on the wider

bottom flange of the Asymmetric beam.

With typical unpropped spans extending to 6 metres and

propped spans to 9 metres the deep decks provide clear

open space between beams. The deck is contained within

the beam depth, which provides a very shallow floor zone.

The shape of the deck profiles allow for service integration

and the whole system provides inherent fire resistance.

ComFlor 46

Nestable

The ultra efficient nesting capability

of ComFlor 46 reduces the

transport volume of the product.

This fact combined with the

simplicity of ComFlor 46 also

makes it ideal for export.

Easy service suspension

Ceilings and lightweight services

can easily be attached to the

punched hangar tabs, which can be

included with ComFlor 46. These

must be specified at time of order.

Low concrete usage

The trapezoidal shape profile of

ComFlor 46 reduces the volume

of concrete used, with resultant

savings in structural and foundation

costs.

Quick reference tables

The quick reference load/span and fire design

tables, on the following 2 pages are intended as

a guide for initial design, based on the

parameters stated below the tables. Full design

can be carried out using the free Comdek

software. Please refer to page 70 for help on

using the software.

Anti-crack mesh

BS 5950: Part 4 currently recommends that anti-

crack mesh should comprise 0.1% of slab area.

The Eurocode 4 recommendation is that anti-

crack mesh should comprise 0.2% of slab area

for unpropped spans and 0.4% of slab area for

propped spans. The mesh shown in the quick

reference tables complies with EC4 and the

design program defaults to these values. Where

EC4 mesh rules are used, the mesh may be

reduced midspan - see Design Information on

page 32. The reduced British Standard mesh

values may still be used by overriding this default

in the design program.

Where forklift truck (or other similar concentrated

loading) is expected 0.5% minimum percentage

reinforcement should be used over the supports

and 2% elsewhere to control cracking. For

further information refer to Design Notes on

page 32 or SCI AD150.

Mesh top cover must be a minimum of 15mm,

and a maximum of 30mm. Mesh laps are to be

300mm for A142 mesh and 400mm for A193,

A252 & A393 mesh.

Fire

For details of the performance of composite

slabs comprising ComFlor 46 decking under

a fire condition with nominal anti-crack mesh,

please refer to the quick reference fire load tables

in this brochure. For other simplified design

cases or for full fire engineering, refer to the

Comdek software.

Parameters assumed for quick reference span tables

Mesh See notes on page 7

Spans Measured centre to centre of supports.

Deck Standard deck material specification (see previous

page).

Bearing width The width of the support is assumed to be 150mm.

Prop width Assumed to be 100mm.

Deflection Construction stage L/130 or 30mm

(ponding has been taken into account).Deflection Composite stage L/350.

Concrete grade The concrete is assumed to be Grade 35 with a

maximum aggregate size of 20mm. The wet weight of

concrete is taken to be normal weight 2400kg/m3

and

lightweight 1900 kg/m3. The modular ratio is 10 for

normal weight and 15 for lightweight concrete.

Construction load 1.5 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 design notes.

Applied load The applied load stated in the tables is to cover

imposed live load, partition loads, finishes, ceilings and

services. 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 The fire recommendations in the tables are based on

design method the simplified design method.

Fire engineering The fire engineering (FE) method may be used to

method calculate the additional reinforcement needed for fire,load and span conditions beyond the scope of these

tables. The FE method of design is provided in the

design CD.

Fire insulation The minimum slab thickness indicated in each table,

for each fire rating satisfies the fire insulation

requirements of BS 5950: Part 8.

Span/depth ratio Slab span to depth ratio is limited to 30 for lightweight

concrete and 35 for normal weight concrete.

Shear studsThe wide trough of ComFlor 51

permits a flexible and efficient

placement of shear studs.

Fire performance of the

composite beams

Even for two hours fire rating, the

top flange of the steel beam does

not require fire protection, when

used with ComFlor 51 composite

deck.

Under floor servicesServices are easy to attach to

ComFlor 51, with the ribs

presenting a dovetailed recessed

groove in the concrete slab at

152.5mm centres. This provides the

perfect connection for service

hangars via a wedge nut or similar

type device.

Fire performance of the slabThe dovetail presents a very small

opening and contributes little to the

transfer of heat through the slab in

the event of fire. Thus a lesser slab

depth is needed for fire design

purposes.



ComFlor 51 is a traditional dovetail re-entrant composite

floor deck. This profile provides an excellent mechanical

key into the concrete slab, offering a strong shear bond

performance, which is augmented by cross stiffeners

located in the profile trough. ComFlor 51 presents a

virtually flat soffit and a relatively thin slab is required to

meet fire design requirements.

ComFlor 80

Central stud placement provides

superb composite action between

the beam and concrete due to the

stud being positioned exactly in the

centre of the trough. This ensures

the correct concrete cover to the

stud and hence, the full design

capacity of the stud is developed.

The central location of the stud also

reduces on-site checking to ensure

that the stud has been positioned

correctly.

Ideal for car parks

ComFlor 80 is available with a

Colorcoat pre-finished steel

underside for use in car parks,

giving a durable and attractive

appearance and minimising future

maintenance.

Excellent concrete usage means

that ComFlor 80 is very economical

compared to other similar decks.

Improved manual handling

The cover width of ComFlor 80 is

600mm, to reduce sheet weight and

improve handling.

The innovative profile design provides real benefits.

ComFlor 80 is fully tested with the

ComFlor 80The next generation of

profiled steel composite decks


ComFlor 80 is the next generation of profiled steel

composite decks; it is the only 80mm profile available in

Colorcoat pre-finished steel to provide a durable and

attractive appearance.

The large corner curvature detail provides a very efficient

profile. In conjunction with the higher grade of steel, it ensures

typical unpropped spans of 4.4m simply supported and in the

continuous condition, spans of 5m can be achieved.

The large spans achievable means less structural steel

and thus cost saving in the overall construction cost,

providing more scope for architects and engineers in their

design process.

ComFlor 60 and 80For use in car parks


Uniquely for a composite floor profileComFlor 60 and 80 can be manufactured with Colorcoat

pre-finished steel coating to the underside. This is suitable for

situations where a visibly exposed soffit is required, such as in

multi-storey car parks. The ComFlor soffit can be left exposed

or where further protection is required it can form the base

coat for further protective systems.

Performance of ComFlor 60 and 80 Soffit

The ComFlor soffit is manufactured using Colorcoat

Exterior Flexible Polyester pre-finished steel. The product

has good formability and durability in exterior application.

It has a Galvatite substrate to BS EN 10326 with a zinc

metallic coating offering good corrosion resistance.

An overall prediction of soffit performance in a

semi-external environment is not possible due to the

variation in conditions that inevitably apply to different

applications.

The 25 micron polyester coating on its own will be

satisfactory in a dry and unpolluted environment (such as

would be expected on most car park soffits) and will only

require regular inspection or assessment after a period of

ten years.

For more challenging applications, an over-paint system

with a suitable performance specification could be applied

post construction. For further advice on sustainability

and suitable paint systems contact Corus technical hotline

on 0845 30 88 330.

Use of (pre-finished) steel decking withcomposite beams

Through deck welded shear studs cannot be used with

pre-finished deck, however various alternative options

are available.

1. Use shear connectors that are attached to the beams

without the need for welding. A number of connectors

that use shot-fired pins are available.

2. Weld the studs to the beams in the fabrication shop, prior

to applying the corrosion protection. With this solution

the decking is laid in single span lengths and butted upto the studs.

3. Use non-composite beams.

4. Use a combination of non-composite secondary beams

and composite primary beams. The decking can then be

laid in continuous lengths across the secondary beams,

which are normal to the span of the primary beams.

Application example:

ComFlor

in Car ParksCorus ComFlor composite floor decking offers the same

benefits to car parks as to other steel framed buildings.

Primarily these are speed of erection and reduced carriage

requirements. Furthermore the reduced structure weight,

height, and the provision of a working platform during

construction can be very significant advantages.

Durability of metal decking in car parks

Galvatite is the standard protective coating for composite

steel decking, giving a sufficient level of corrosion

protection to the upper surface of the decking, provided

adequate provision has been made to prevent the ingress

of water (using reinforcement to control cracking, and

waterproofing to the top surface of the concrete). The top

deck of the car park should be waterproofed with a

traditional bituminous membrane or liquid applied seamlesscoating. It is also good practice to treat other floors to

prevent ingress of water from above. Adequate falls and

drainage should be provided, to prevent the build up of

water on the slabs.

The underside of the decking may additionally be

pre-finished (such as ComFlor with Colorcoat Exterior

Flexible Polyester) or by using epoxy paint applied in situ,

in order to provide a contemporary appeal or additional

protection. Corus will provide advice on durability or future

maintenance depending on the preferred post-finish.

Car park roof

Car parks, but more importantly their users, will benefit from

protection against the external climate.

There is a growing trend to use a lightweight roof over the

top parking deck. This gives added protection to the top

floor of the car park allowing users to park in all weathers.

The aesthetic appeal of a car park can be significantly

enhanced by this method enabling the car park to blend in

with the urban environment. The long-term benefits of

reduced maintenance can far outweigh the initial cost ofthis approach. The car parks at Aylesbury and Guildford

typify this method of construction.

Corus publication Steel-framed car parks

The comprehensive Corus brochure Steel-framed car

parks, is available free from Corus Construction &

Industrial tel: 01724 405 060.

This publication covers all aspects of steel-framed car park

design including outline, circulation, structural form, fire

resistance, durability, aesthetics and commercial viability.

ComFlor 100

No temporary propsComFlor 100 can carry wet

concrete and construction loads to

4.5m without temporary propping,

(depending on slab depth) thereby

leaving a clear area beneath the

floor under construction. Further

savings of labour and prop hire are

also realised.

Large concrete volume reductionAlthough a deep slab is required,

the ComFlor 100 profile greatly

reduces the volume of concrete

needed and thus the cost and

weight of concrete.

Suitable for traditionalconstruction

ComFlor 100 is suitable to be

placed onto masonry walls or

standard design non-composite

steel beams.



ComFlor 100 has a very strong profile shape and offers

the capability to span up to 4.5 metres without props.

Designed particularly for Continental European

application, the ComFlor 100 also brings considerable

benefits to the British designer looking for longer

unpropped spans. The profile is not suitable for use with

shear stud connectors.

In recognition of the many practicaldifficulties associated with the use of

traditional welded wire fabric in upper

floor construction and in response to

the ever increasing demands for

improved speed of construction,

improved quality and cost

effectiveness, Corus and Propex

Concrete Systems have joined forces

to develop FibreFlor.

FibreFlor is a combination of Novocon

high performance steel fibres and

Fibermesh micro-synthetic fibres

providing a unique three dimensional

concrete reinforcement solution for

composite metal decks and designed

to replace traditional welded wire

mesh.

By combining the attributes of both

types of fibre, FibreFlor provides

performance benefits over the entire

life span of the concrete from

simplifying placement, to minimising

cracks in the plastic state, to

controlling cracks in the hardenedstate, to providing years of

exceptional durability.

In the development of FibreFlor, it was

identified that many properties were

required to provide both an optimum

technical solution for the necessary

fire rating, but also practically in

providing a concrete solution that is

easily handled, pumped and finished.

The world leading brand of Fibermeshmicro-synthetic fibres are proven to

inhibit both plastic shrinkage and

settlement cracking. Additional

benefits include increased impact and

abrasion resistance together with

reduced permeability of the concrete.

Fibermesh micro-synthetic fibres are

also internationally proven to provide

resistance to explosive spalling, in the

event of fire.

Novocon high performance steel

fibres are proven to provide both a

high level of ductility to the concrete

and long term crack control. Thisallows the load carrying capability to

replace traditional mesh

reinforcement. Testing approved by

the Steel Construction Institute

confirmed that FibreFlor also provided

longitudinal shear resistance in excess

of that provided by A393 steel wire

fabric.

FibreFlor reinforced composite metal

deck systems have been extensively

tested in accordance with BS EN

1365-2:2000 standards at NAMAS

certified fire test facilities, under the

guidance of the Steel Construction

Institute (SCI).

Results, analysed and approved by

the SCI, show that FibreFlor

reinforced composite metal deck

systems provide equivalent or

superior performance to traditional

wire mesh solutions with fire ratings of

up to two hours.

Design Information

Shallow Composite Floor DecksDesign Information

Design Parameters Fire rating dictates minimum

slab depth.

Concrete type also dictates

minimum slab depth

and influences

unpropped

deck span.

Deck span (unpropped) usually

dictates generalbeam spacing.

Slab span (propped deck)

dictates maximum

beam spacing.

Two Stage Design

All Composite Floors must be considered in

two stages.

Wet Concrete and construction load

carried by deck alone.

Cured concrete

carried by composite slab.

General design aims

Generally designers prefer to reduce therequirement to provide temporary propping

and so the span and slab depth required

governs the deck selection. Fire

requirements usually dictate slab depth. For

most applications, the imposed load on the

slab will not limit the design.

Quick Reference and full design.

The combination of this manual and

Comdek software makes both quick

reference and full design easy. Indicative

design may be carried out from the printed

tables, however the software greatly

increases the scope available to the design

engineer and allows the engineer to print afull set of calculations which can be used for

submission to a Local Authority.

Anti-crack mesh

FibreFlor can be used to replace anti crack

mesh. Where mesh is used, BS 5950 : Part

4 recommends that it comprises 0.1% of

slab area. The Eurocode 4 recommendation

is that anti-crack mesh should comprise

0.2% of slab area for unpropped spans and

0.4% of slab area for propped spans. The

mesh shown in the quick reference tables

complies with EC4 and the design program

defaults to these values. The reduced BS

mesh values may still be used by overridingthis default in the design program.

In slabs subject to line loads, the mesh

should comprise 0.4% of the cross-sectional

area of the concrete topping, propped and

unpropped.

These limits ensure adequate crack control

in visually exposed applications (0.5 mm

maximum crack width). The mesh

reinforcement should be positioned at a

maximum of 30 mm from the top surface.

Elsewhere, 0.1% reinforcement may be used

to distribute local loads on the slab (or 0.2%

to EC4).

Mesh laps are to be 300mm for A142 mesh

and 400mm for A193, A252 & A393.

Forklift trucks

Where forklift truck (or other similar)

concentrated loading) is expected 0.5%

minimum percentage reinforcement should

be used over the supports and 0.2%

elsewhere to control cracking. For further

information refer to SCI AD150.

Exposed floors

Composite floors are usually covered by

finishes, flooring or a computer floor; andbecause cracking is not visible, light top

reinforcement is adequate, typically 0.1% of

the gross cross sectional area. However

where the composite slab is to be left

uncovered, e.g. for power trowelled floor

finishes, cracking, particularly over the

beams, may not be adequately controlled by

the light mesh usually provided. The

cracking has no structural significance, but

the appearance of it, and the possibility of

the crack edge breakdown under traffic, may

be perceived as problems. In this case, refer

to Concrete Society publication, 'Cracking In

Composite Concrete/Corrugated Metal

Decking Floors Slabs' which provides valid

mesh sizing and detailing for specific crack

width control. Where forklifts are to be used

also refer to Steel Construction Institute

advisory note 'AD 150, Composite Floors -

Wheel Loads From Forklifts'. Both

publications are available from our Technical

Advisory Desk.

Reduced mesh

Where EC4 mesh rules are used, as

recommended by Steel Construction

Institute and Corus, the full stipulated mesh

applies to the slab 1.2m either side of every

support. Outside of this, i.e. in the midspan

area, the mesh area may be halved (to 0.2%

for propped and 0.1% for unpropped

construction), provided there are no

concentrated loads, openings etc. to be

considered. Also the reduced midspan mesh

must be checked for adequacy under fire,

for the rating required.

Bar reinforcement

The axis distance of bar reinforcement defines

the distance from the bottom of the ribs to thecentre of the bar, which has a minimum value

of 25 mm, and a maximum value of the profile

height. Where used, bar reinforcement is

placed at one bar per profile trough.

Transverse reinforcement

Corus composite floor decks contribute to

transverse reinforcement of the composite

beam, provided that the decking is either

continuous across the top flange of the steel

beam or alternatively that it is welded to the

steel beam by stud shear connectors. For

further information refer to BS5950:Part 3:

Section 3.1.Clause 5.6.4.

Concrete choiceLightweight concrete (LWC) uses artificially

produced aggregate such as expanded

pulverised fuel ash pellets. LWC leads to

considerable advantages in improved fire

performance, reduced slab depth, longer

unpropped spans and reduced dead load.

However, LWC is not readily available in

some parts of the country. Normal weight

concrete uses a natural aggregate and is

widely available.

The strength of the concrete must meet the

requirements for strength of the composite slab

and shall not be less than 25N/mm2 for LWC or

30N/mm2 for NWC. Similarly, the maximum

value of concrete strength shallnot be taken as greater than 40 for LWC or

50 for NWC.

Composite floor decking design is generally dictated by the construction stagecondition, the load and span required for service and the fire resistance required for

the slab. The deck design is als
