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
= 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

10Threading 500PLUS REBAR
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 valuesof 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 nominal tensilestrength equal to 0.85 x 540 = 459 MPa.* Denotes second choice thread size. Nuts may be difficult to obtain. N.B. Engineers should beaware that threading reinforcing bars this way also reduces the ductility to less than theminimum requirements for Class N bars specified in AS/NZS 4671.

The nominal internal diameter of a reinforcement bend or hook shall be taken as thediameter of the pin around which the reinforcement is bent. The diameter of the pinshall be not less than the value determined from the above table as appropriate:
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 135o or 180o bend 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 thesame total length as required for a 180o hook of the same diameter bar.

16Bending & Rebending
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 ispreferably performed at ambient temperature, as this has theleast effect on steel properties. Please observe the following:• The initial bend should be performed around a mandrelor 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 diameternot 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, but areduction 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
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 useof 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 bentii) the temperature of the steel does not exceed 600oCiii) the bar is not cooled by quenching

30500PLUS BAMTECReinforcing Carpets
BAMTEC is the world’s fastest steel fixing system. It involvesdesigning and prefabricating reinforcing steel “carpets” to awide 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 complexshapes and penetrations.
When needed on site, the carpet is simply lifted into place andunrolled onto continuous bar chairs.
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
31www.reinforcing.com
Size limits
The minimum diameter of bar which can be used withBAMTEC is 10mm. The largest diameter used is 32mmClass N 500PLUS REBAR.
The minimum bar spacing is 50mm up to a maximumspacing of 400mm. BAMTEC comes in widths from1.8m minimum to 15m. Maximum mass per carpet isapproximately 1.6 Tonne.
32HANDIMESH
HANDIMESH is a range of general purpose welded meshproducts. Available in 21 different specifications including:• Pre-galvanised & bright wire• Sheets & Rolls• Half and full sheetsIdeal for fencing, shelving, security, gates, safety,guarding and point-of-sale and is flush cut, savingyou time in trimming.
