Quick Reference Table – Tension Lap Lengths
Choose the section of the table with the relevant cover and concretestrength (f’c) on the same line, refer to this section for the tension laplength relating to the bar diameter listed in the two shaded sections(refer below for shading). If the required cover or concrete strength isnot listed use the closest lower values of cover and concrete strength.
Common bar chair sizes (mm) are: 20, 25, 30, 40, 50, 65, 75+
In AS3600, clause 13.1.2.1 states that the development length (Lsy.t)to develop the yield strength (fsy) of a deformed bar in tension shallbe calculated as follows:
Lsy.t =k1k2fsy Ab
(2a + db)√f’c≥ 25k1db where
k1 = 1.25 for a horizontal bar withmore than 300mm of concrete castbelow the bar; or
= 1.0 for all other barsk2 = 1.7 for bars in slabs and walls if
the clear distance betweenadjacent parallel bars developingstress is not less than 150mm or > 150mm
= 2.2 for longitudinal bars in beamsand columns with fitments
= 2.4 for any other longitudinal bar
fsy = the yield strength of the reinforcingbar
Ab = the cross sectional area of thereinforcing bar
2a = twice the cover to the bar or theclear distance between adjacentparallel bars developing stress,whichever is less
db = the nominal diameter of a barfc = the characteristic compressive
cylinder strength of concrete at 28 days

10Threading 500PLUS REBAR
www.reinforcing.com
The design tensile strength of fine-threaded 500PLUS REBAR (φNtf) canbe determined in accordance with AS4100 Steel Structures. Based onthe results of testing, fine-threaded 500PLUS REBAR has reducednominal yield strength equal to 75% of the nominal yield strength (500 MPa) and a reduced nominal tensile strength equal to 85% of thenominal tensile strength (540 MPa) based on the thread stress area.
It follows that OneSteel 500PLUS REBAR, when cut with AS1275 metricthreads and fitted with AS1112 Property Class 5 nuts, has the values of design tensile strength (φNtf) specified in the adjoining table. Thesedesign tensile strengths are based on the effective tensile stress areasfrom AS1275, a strength reduction factor φ = 0.8, and a nominaltensile strength equal to 0.85 x 540 = 459 MPa.* Denotes second choice thread size. Nuts may be difficult to obtain. N.B. Engineers should be
aware that threading reinforcing bars this way also reduces the ductility to less than the minimum requirements for Class N bars specified in AS/NZS 4671.

A standard hook or cog provides half of the tensile development length for that end of the bar, measured from the end of the bar.
A standard hook consists of a 135oor 180
obend around the appropriate pin with a straight extension of:
-10db or 100mm whichever is greater for shear reinforcement in beams
- 8db or 140mm whichever is greater for plain round bars
- 4db or 70mm whichever is greater for all other applications
A standard cog consists of a 90o
bend around the appropriate pin, but not greater than 8db having the
same total length as required for a 180o

500PLUS REBAR

Bending/Rebending & Welding Practice Notes
A number of situations may arise where bars must be bent orrebent on site, or where pre-bent bars must be straightened. For smaller diameter bars (i.e., 10, 12 & 16mm), this is preferably performed at ambient temperature, as this has the least effect on steel properties. Please observe the following:• The initial bend should be performed around a mandrel
or former of diameter specified in the relevant code, andgenerally not less than 4db.
• Rebending or straightening should be performed using apowered bending tool, or a pipe with internal diameter not greater than 2x the nominal bar diameter.
• Do not use impact blows to bend or rebend the steel.• Take care to minimise surface damage and
visually inspect rebent area for cracks.
For larger diameter bars, the application of heat (e.g. from anacetylene flame) may be used to reduce the bending force, buta reduction in bar strength may result.
Further details on bending/rebending & welding 500PLUS REBARcan be found at www.reinforcing.com
A pipe must not be used to make the initial bend, or to rebend back past thestraight position. Rebending of bars that have been bent prior to galvanising isnot recommended, as cracking on the inside of the original bend may result.

18Heating & Welding 500PLUS REBAR
www.reinforcing.com
iv) if during heating the temperature of the bar exceeds 450oC, the designyield strength of the steel after bending shall be taken as 250 MPa.
Welding
500PLUS REBAR produced by the TEMPCORE process and microalloyed500PLUS coiled rebar has a maximum carbon equivalent (Ceq) of 0.44.max and, as such, requires no pre-heating prior to welding. Pre-heatingis not required when welded in accordance with the AS/NZS1554 part3. Hydrogen controlled electrodes will be required for all weld types,and matching strength electrodes will be required for butt welds.
Note: Some types of welded splices can reduce the ductility of theconnected bars.
After heating, the resulting ambient temperature properties ofreinforcing steels may be significantly altered. This is an importantconsideration if heat has been applied to assist with bending bars,through welding, or the effect of fire. To effectively manage thetemperature control during the heating or welding process the use of temperature control crayons is recommended.
Heating
Heating should be avoided if the original bar properties are required.Bending should always be around a former of the appropriate size(refer processing to AS3600). AS3600 states in clause 19.2.3.1 thatreinforcement may be bent hot, provided that:i) the steel is heated uniformly through & beyond the portion to be bent ii) the temperature of the steel does not exceed 600oC iii) the bar is not cooled by quenching

30500PLUS BAMTEC
Reinforcing in a Roll
www.reinforcing.com
BAMTEC is the world’s fastest steel fixing system. It involvesdesigning and prefabricating reinforcing steel “carpets” to a wide range of shapes and sizes.
Individual rebars are welded to flexible steel straps, which canconnect up to hundreds of bars together, and the carpet is rolledup for handling and transport.
The carpets can contain different types and sizes of bars, havebars at different spacings and can accommodate complex shapes and penetrations.
When needed on site, the carpet is simply lifted into place andunrolled onto continuous bar chairs.
Size limits
The minimum diameter of bar which can be used withBAMTEC is 10mm. The largest diameter used is 32mm Class N 500PLUS REBAR.
The minimum bar spacing is 50mm up to a maximumspacing of 400mm. BAMTEC comes in widths from 1.8m minimum to 15m. Maximum mass per carpet isapproximately 1.6 Tonne.
Benefits
• Super-fast construction• Save up to 80% on steel-fixing costs• Ideal for suspended slabs, slab on ground,
CRCP and tilt-up panels• Improves cost effectiveness of slab construction• Variable spacing and bar diameters available• Improved accuracy and quality• Less material waste and scrap• Design assistance available• Less bending and carrying• Easier chairing and no bars to sort• Simpler marking plan

• STUDMESH is a joint OneSteel Reinforcing and UWS-CCTRcomposite beam innovation for all steel decking systems.
• More efficient than placing individual transverse reinforcingbars or mesh around sheer connectors as longitudinal shearreinforcement.
• Suitable for use in secondary and primary compositebeams, or when the sheeting ribs are parallel on one side,perpendicular on the other.
• Can be designed using Clauses 9.4 to 9.7 of AS 2327.1as Type 1, 2 or 3 longitudinal shear reinforcement
• DECKMESH is a joint OneSteel Reinforcing & UWS-CCTRcomposite beam innovation
• Satisfies Clause 9.8 of AS 2327.1 Simply Supported CompositeBeams regarding reforcing secondary composite edge beamsagainst Type 4 (rib-shearing) longitudinal shear failure.
• Prevents concrete pull-out failure when trapezoidal decks likeKF70 are used with stud pairs in internal secondary beams.
• No design calculations required to specify DECKMESH toprevent rib-shearing or concrete pull-out failures when used with welded studs.

36HAUNCHMESH Composite
Shear Reinforcement
www.reinforcing.com
• HAUNCHMESH is a composite beam innovation madeunder exclusive licence by OneSteel Reinforcing.
• Welded studs need to be spaced longitudinally in singlesor doubles to match the spacing of the transverse bars in standard HAUNCHMESH STRAIGHT panels
• Controls longitudinal splitting, prevents lateral punch-outof concrete in haunch and ensures welded studsarranged in singles achieve solid-slab strength status.
• Minimum concrete haunch width with split decking equals220mm (KF70) or 240mm (W-DEK) at base, and studs must be centred in haunch.
• Availale for KF70 with unsplit decking and narrow 136mm wide haunch
• Type 1,2 or 3 longitudinal shear reo (Clause 9.7 of AS 2327.1)
