2.3 Materials

All purlins are rolled using BlueScope SteelGALVASPAN® high tensile steel. This product has astandard galvanized coating of Z350 (350 grams ofzinc per m2) and is typically used in non-aggressiveareas. For severe and aggressive environments wherea build-up of airborne corrosive contaminants canaffect the coating, Z450 is recommended (450 gramsof zinc per m2). The following table lists the SteelGrade for each steel gauge;

Table 22.3

2.4 Lapping requirements

In order to ensure continuity in lapped span systems,lap lengths should be of an adequate distance and besubstantially connected. For lapped purlin systems thelength of the lapped region over each support is 15%of the span (ie 7.5% of the span on each side of thesupport). In order to achieve satisfactory connectivity atthe lap each end of the lap must have one bolt throughthe flanges farthest from the cladding and another boltthrough the webs at the end of the webs closest to thecladding. For further advice on this boltingarrangement, contact a Fielders technicalrepresentative.

2.5 Bolts

Fielders supply grade 4.6 bolts. It has been assumedin the preparation of the capacity tables within thisDesign Manual that the purlins are connected throughthe web of the purlin to cleats. Purlins of depths lessthan 300mm require two M12 bolts and purlins ofdepth 300mm or greater require two M16 bolts.Typically purlin span configurations require grade 4.6bolts, however numbers shown in bold italics in thecapacity tables in section 10.0 require grade 8.8 bolts.

2.6 Standard Punching

22 x 18mm slotted holes will be punched when usingstandard grid line centres of 40, 60, 110, and 160.Flange punching is also available.

2.7 Non-Standard Punching

Non-standard punching and non-standard roundholes are available and are subject to negotiation withFielders.

Fielders detailing sheets are available as a service tothe industry and may be obtained by contacting yourlocal Fielders office.

5.0 Bridging

The purlin capacity tables in this Design Manual havebeen prepared in consideration of the followingbridging locations along the length of the purlin.

Table 55.1

The Fastlock Bridging System for custom punchedpurlins and girts consists the following range ofbridging series;

• IB series Intermediate Bridging• FB series Fascia Bridging• SB series Support Bridging• RB series Ridge Bridging• GH series Girt Hanger Bridging

About BBridging

The bridging network should be locked into positionprior to the commencement of fixing roof and wallcladding. Failure to meet the requirement may result inthe permanent twisting of the unrestrained websections.

Twisted or distorted webs, in addition to being visuallyunacceptable, may greatly reduce the load capacity ofthe total system.

Consult the capacity tables for design details.

5.1 IB Series Intermediate Bridging for Custom Punched Purlin & Girt Systems

IB BBridgingThe IB bridge is identified by the distinctive ‘hook &locator’ brackets. Units are produced with both bracketspress fixed to a channel spacer. When detailing lengthrequirements, it is only necessary to nominate the purlinor girt spacing minus 3mm as shown in Diagram B.Capacity Tables should be consulted for bridgingconfigurations. Fastlok IB bridging is available in the100IB, 150 IB and 200 IB series only.

ErectionIB bridging is required between each spacing of purlinsand girts. Always keep the ‘hook’ and bracket in thedownward position. Working up the roof slope or fromfloor level insert the ‘hook’ through the ‘locator’ of thepreceding bridge, repeat until all units are completed.The ‘hook’ is normally entered at about 15° – 20° angleto the purlin or girt web.

When erecting IB bridging to wall girts ensure that SBsupport bridging or GH bridging have been installed.

Note:It is important to distribute temporary working loadswhile erecting bridging to purlins. A suitable plank laidover a minimum of 4 or 5 purlins is adequate. Ensurethat unbroken roof sheeting packs are off loaded overstructural supports, not mid span.

IB bridging is available to suit all spacing requirements.

5.2 FB Series Fascia Bridging for Custom Punched Purlin & Girt Systems

FB bridging is produced with fully adjustable telescopicchannels and slotted end brackets. This enablesaccurate adjustment when aligning fascias and othertermination members. When detailing FB bridging,nominate the spacing between the end purlin andfascia while channels of appropriate combined lengthwill be supplied. On occasions, only one channel maybe required.

ErectionFB bridging should be erected before IB or RB bridgingis commenced. The unit is bolted to the fascia, whilethe opposite end bracket provides the locator throughwhich the Fastlok ‘hook’ is engaged. When the totalbridge network has been installed the fascia channel isaligned and FB component bolts tightened. Whenopposite hand FB bridging is required, remove TBbracket and rotate.

The FB bridge, when used at the head of a skillionframe must be bolted to the adjacent IB bridge, (seeinset).

5.3 SB Series Support Bridging forCustom Punched Purlin & GirtSystems

SB SSeriesDesigned to support the first wall girt at floor level, theSB bridge is also useful when the accurate length offixed end bridging is difficult to calculate. Oncompletion of the concrete floors the SB bridgingshould be inserted and bolted to the slab (concretefixings by others).

This ensures that wall girts are held straight before theIB bridging is commenced. Unsupported girts result inunsatisfactory sagging of cladding and glazing.

If unable to use SB bridging (eg. no floor slab), girtsmust be supported from fascia bridging using GHBridging (see diagram C).

Note: If measurement A less than 150mm use BEB endbrackets in combination consult Fielders TechnicalRepresentative for further details.

7.0 Design Capacity Tables

7.1 Assumptions

The information contained within the followingcapacity tables and the associated sectional propertieshave been determined in accordance with AS/ANZ4600:1996 Cold-formed steel structures.

The design capacity tables have been prepared basedon the following assumptions:• The loads applied to the purlins act parallel to the

Y-axis of the Z or LC section.• The loads are applied uniformly to the top flange

of the purlin.• The members behave in accordance with the

simple theory of bending.• The roof sheeting is screw fastened to the top

flange of the purlins to provide diaphragm shearstiffness but not torsional restraint to the purlins.

7.2 Loads

The loads provided in the capacity tables are uniformlydistributed and interpolation between spanconfigurations is allowed.

The determination of loading conditions must be madeon a project specific basis and is outside the scope ofthis Design Manual. It is essential that the user of thisDesign Manual have the loading conditions for thedesign case calculated and verified by a qualifiedprofessional taking into consideration the appropriatestandards and codes.

For project specific cases where point loads areapplied to the purlins, an equivalent uniformlydistributed load can be determined using Table 7.1and then selecting the appropriate number from thedesign capacity tables.

7.3 Notes to Capacity Tables

• All spans are in mm.• Linear interpolation of capacities is allowed.• The uniformly distributed load (UDL) for

deflection in mm of span/150 is the load for thespan that results in a value for deflection ofspan/150. It must not be confused with thedesign capacity of the member.

• k is a factor that when multiplied by the designload in kN/m results in an approximate value forpurlin deflection in mm. Interpolation of the k factor between spans is not allowed. The kfactor assigned to the first tabulated span greaterthan the design span shall be used in all cases.

• Loading capacities• Inward = inward loading capacity - assumesthe load is acting to force the cladding againstthe structure, measured in units of kN/m where 0= no bridging, 1 = 1 row of bridging, 2 = 2rows of bridging and 3 = 3 rows of bridgingplaced at locations along the span inaccordance with Table 5.1 in Section 5.0.• Outward = outward loading capacity -assumes the load is acting to force the claddingaway from the structure, also measured in unitsof kN/m• The tables do not include capacities less than0.4 kN/m and where additional bridgingprovides less than 2% additional capacity novalue is stated.

• Values shown in bold italics indicate therequirement to adopt grade 8.8 bolts, otherwisegrade 4.6 bolts are assumed.

For purlin depths less than 300mm, 2 x M12bolts are required and for depths 300mm orgreater 2 x M16 bolts are required.

• The capacity tables assume that the FastLockBridging system is adopted.
