F22 SmartBrace Design Guide 1 June 2023SmartBrace®Design GuideEdition 12023F22 SmartBrace Design Guide 2 June 2023Scope of this Design GuideThis Design Guide assists users to design interpret Table 8.18 within AS 1684.2—2021 to calculate the bracing capacity for F22SmartBrace brace ply for most of the common structural arrangements in domestic construction.The SmartFrame software in conjunction with AS 1684 providestools for calculating the racking forces on buildings.While specific details are given on suitable methods of developingracking resistance, the methods of providing adequate diaphragmsupport, overall anchorage against wind uplift and overall structural stability are outside the scope of this publication. Informationon the above matters can be obtained from AS 1684 Residentialtimber-framed construction code or from a structural engineerexperienced in timber construction.Tilling Timber Pty Ltd has structural engineers on staff who can becontacted for advice on matters concerning the use of its engineered timber products in timber construction on the TechsupportCustomer helpline on 1300 668 690 or at techsupport@tilling.com.au.Basis of stated capacitiesThe information contained in this product brochure is current as atMay 2023 and is based on data available to Tilling Timber Pty Ltdat the time of going to print.The bracing capacities for F22 SmartBrace manufactured for TillingTimber within this document are interpolated from Table 8.18 ofAS 1684.2-2021, and have been confirmed with individual testingto ASTM E72 carried out at Universal Testing Facility Pty Ltd (UTF)in Dandenong South for alternative stud spacing’s, where applicable.AS 1684.2-2021 is a primary reference document in the NCC and isa therefore a “deemed to satisfy” solution.Tilling Timber Pty Ltd has used its reasonable endeavours to ensure the accuracy and reliability of the information contained inthis document and, to the extent permitted by law, will not beliable for any inaccuracies, omissions or errors in this informationnor for any actions taken in reliance on this information.Tilling Timber Pty Ltd reserves the right to change the informationcontained in this document without prior notice. It is importantthat you call the techsupport customer helpline on 1300 668 690to confirm that you have the most up to date information available.CopyrightCopyright of this publication remains the property of Tilling TimberPty Ltd, and reproduction of the whole or part of this publicationwithout written permission from Tilling Timber Pty Ltd is prohibited.F22 SmartBrace propertiesF22 SmartBrace brace ply is made from Chain of Custody Certifiedplantation Eucalypt veneers manufactured by Furida Wood Co.Ltd. The manufacturing is carried out under third party auditedprocess control with in-factory testing in the factory’s laboratory,and further third party testing of the Type A bond quality, F gradeand formaldehyde emission at the University or Technology Sydney (UTS).Compliance with process based quality control requirements is third party auditedby SAI- Global, and the audits,together with end producttesting, is used as the basis forProduct Certification by SAIGlobal as a JAS-ANZ accreditedProduct Certification body.JAS-ANZ stands for the government established “JointAccreditation System of Australia and New Zealand” which existsas the peak organisation for accreditation of Product Certification.FeaturesF22 SmartBrace is a new and innovative bracing product manufactured from plantation Eucalypt hardwoods from certified forestsand is an economical replacement for tropical rainforest plywoodspredominantly sourced from South East Asia, some with unknownprovenance.It is a strong and durable raw, H2s or H2 preservative treated engineered wood panel (can be post production treated to H3), a trueHigh Performance hardwood plywood complying to AS/NZS 2269.ApplicationsF22 SmartBrace is designed to resist horizontal racking forces applied to buildings such as cavity bracing in external wall frames inbrick veneer construction, and to resist uplift in braced walledsystems.Ordering F22 SmartBraceTimber framingTimber wall frames should comply with government building regulations and where applicable AS 1684. Framing members shouldbe minimum F5 stress grade and joint strength group or JD5(seasoned). Stud spacing’s should not exceed 600 mm centres for1200 mm sheets and 450 mm centres for 900 mm sheets.The resistance values in the enclosed tables are based upon fixingthe sheeting to framing having a minimum joint strength of JD5.Where the timber framing is of joint strength of JD4, racking resistance for the F22 SmartBrace systems in this Design Guide maybe increased by 12.5%.It is essential for the bracing walls to be securely connected to theroof and sub-floor systems. Wind forces acting on the roof mustbe resisted and transferred to the ceiling diaphragm and throughthe walls to the sub-floor. The methods of connection are detailedin AS 1684, and include nail fixings, galvanised iron straps, framinganchors and bolts.SMK40624AS/NZS 2269.0F22 SmartBrace®F22 SmartBrace size PiecesperpackAreaper pack(m2)Weight/panel(kg)Weight/pack(kg)Length(mm)Width(mm)2440 900 150 329.4 5.5 8242440 1200 150 439.2 7.3 10982745 900 150 370.6 6.2 9272745 1200 150 495.7 8.3 12363050 900 150 144.8 6.9 10293050 1200 150 549.0 9.2 1373F22 SmartBrace Design Guide 3 June 2023Weather ExposureDuring normal weather conditions, SmartBrace may be exposedto the weather and subjected to wetting and drying. As the product is supplied in a moisture-conditioned state (seasoned), it isadvisable to enclose the building as soon as possible after fixingthe sheets. A maximum exposure period of three months is recommended.SmartBrace is a wood panel product and therefore some dimensional movement may occur during extended periods of extremely high or low relative humidity.InstallationBefore installation SmartBrace panels should be checked for:1. Correct panel grade and marking2. Correct panel thickness3. Any physical damageF22 SmartBrace should be installed vertically with sheet endsfixed to the top and bottom plates. Support the vertical edgesover studs. F22 SmartBrace like all wood based products is hygroscopic, meaning the panel will adjust to the equilibrium moisturecontent of its environment. To allow for small dimensional movement of the F22 SmartBrace panel, allow a 2 mm gap betweensheets and raise the sheets 2 mm from the floor.Uplift force may require additional fixings at the end of the bracing panel in accordance with AS 1684.Fix sheets with 2.8 mm Ø x 30 mm flat head galvanised or corrosive resistant nail, the fastener head should NOT be driven intothe sheet. When stressing the frame under high loads, the modesof failure are typically nail pull through, failure of the joint between the studs and plates or plate splitting. By staggering thenails, the latter failure is minimised since a common crack line isnot induced in the plate.Simplified bracing for non-cyclonic areasBracing walls are set at right angles to the windward walls. In accordance with AS 1684, they should be evenly distributedthroughout each storey of the building. Bracing shall initially beplaced in external walls, and where possible, at the corners of thebuilding. Where bracing cannot be placed in external walls because of openings or similar situations, a structural diaphragmceiling may be used to transfer racking forces to bracing walls thatcan support the loads.Unless otherwise specified, sheet bracing walls shall be a minimum of 900 mm wide. Clause 8.3.6.5 of AS 1684.2 gives limitedexceptions to this, and these exceptions are described as part ofthe capacity diagrams within this Design Guide.Total bracing requirements for each ‘area of elevation’ of thewindward walls can be obtained from the SmartFrame softwaresuite or alternatively AS 1684 Table 8.2. Ensure that the minimumbracing unit requirements for the external walls are satisfied. Theadditional bracing units can then be evenly distributed throughoutthe external and internal walls.For the number of F22 SmartBrace sheets, divide the bracing unitrequirements by the Design Capacity per sheet width in this Design Guide. Where the building elevation contains combinations ofpitched roofs, gable or skillion ends, or upper or lower storeys,the ‘area of elevation’ of each section should be calculated separately to determine the total bracing unit requirements.Brick veneer constructionF22 SmartBrace is ideal for use as cavity bracing in brick veneerstud construction. Brick wall ties must be the face-fixed type andcomply with AS 2699 – Wall Ties for Masonry Construction. Theties should be nailed through the F22 SmartBrace into the narrowface of the studs.Wall cavities should be kept clear of obstructions and the wall tiessloped downwards, away from the frame and bracing.When constructing boxed eaves, the inner ends of soffit bearersor sprockets should not penetrate through the structural sheetbracing. Hangers suspended from the top wall plate or rafters maysupport the ends.Standard fastenersThe racking capacities of the systems in this Design Guide arebased upon hand driven 2.8 Φ x 30 mm flathead structural cloutsor connector nail, with alternative power nail* options listed below.Fastener edge distances along top and bottom plates and edgestuds should be a minimum of 15 mm and 7 mm where panels arefixed to internal framing.The spacing for staples are two thirds (fastener spacing multipliedby 0.66) of those shown for nails or screws.Stu d cavityWallWal l TiesBric ksHand driven nails Flathead structural clouts or connector nail 2.8 Φ x 30 mmPower driven nails *Coil Nailer NailsBrand Nailer code Description Nail Code Size CollationBeA45800-3567DCWire/plastic nailer32 mm to 65 mm nails45041 FAP32 x 2.5 mm Φ EG Helical twist(clout nail) Plastic45144 FAP32 V5 2.9 mm Φ HDG screw (Clout nail) Plastic45042 FAP38 V5 2.5 mm EG Φ Helical twist (cloutnail) Plastic43500 ANR60 Air anchor nailer 43506 36.5 x 3.3 mm Φ Anchor nails Paper43512 40x 4.0 mm Φ Anchor nails PaperPaslodeB40001 Impulse CoilMaster IM50S B40027 32 x 2.7 mm Φ (Hot Dip Galvanised) 0° CoilB21094 or B21095 CNW 57 or CNW 70.1 CoilNailer B25115 32 x 2.7 mm Φ (Hot Dip Galvanised) 15° CoilBostitch N80CB-1ML Coil nailer 80 mm Max AC45R250-GAL 45 x 2.5 mm Φ galvanised 15° CoilDuoFast D40010 or D40030 CNP 50 or 65.1 Coil Nailer D41810 32 x 2.7 mm Φ (Hot Dip Galvanised) 0° CoilSenco TBC5700 Aico A57 Coil nailerAC45R250-GAL 45 x 2.5 mm Φ galvanised 15° CoilYA45252R AC45R250-GAL HDG Ring Shank45 x 2.5 mm Φ15° CoilF22 SmartBrace Design Guide 4 June 2023Small diameterservice pipe penetration ofapprox 30 mmdiameter shouldbe drilled andnot exceed fourholes per sheetNOpenetrationto timberframingAreas within 300 mm ofcorners should be avoidedLarge service pipe penetrations of upto but not exceeding 50 mm diameterare limited to one hole per sheetStandard fasteners (cont’d)Notes:1. The above power driven nail sizes have been provided by the respective manufacturers to Tilling Timber Pty Ltd as offering an equivalent capacity as the hand driven 2.8Φ x 30 mm Flathead structural clouts or connector nail and while their performance with SmartBrace has not been the subject of individual testing, experience and engineering judgement has been exercised2. This list is offering advice only, and does not preclude any other fastener being used that can be demonstrated to exhibit equivalent capacity as the 2.8 Φ x 30 mm Flathead structural clouts or connector nail3. This list was correct at the time of publication, so users may need to refer to the respective manufacturer if the listed option is no longer available.Wall capacity and height modificationThe racking capacities of the systems in this Design Guide arebased upon a wall height of 2700. For walls of different heights,the capacity shall be multiplied by the value given below:Bracing wall capacity/height modifierPenetrations through SmartBrace panelsShould it be necessary to penetrate the F22 SmartBrace forplumbing or electrical installations, keep the penetrations to aminimum and locate them towards the centre of the sheet. Holesshould always be neatly cut and the corners rounded.Areas within 300 mm of corners should be avoided. Large servicepipe penetrations of up to but not exceeding 150 mm diameterare limited to one hole per sheet. Small diameter service pipepenetrations of approximately 30 mm diameter should be drilledand not exceed four holes per sheet. Holes should be placed asclose as possible to the sheet centre.Sawing, drilling and shapingF22 SmartBrace can be sawn and shaped like solid wood in anyway with standard wood working tools in a well ventilated openarea to avoid breathing wood dust. If hand held equipment without suction is used, a protective face mask should be worn.It is recommended that carbide tipped tools are used to providethe neatest cut without damaging the edge of the F22 SmartBracepanel. Conventional hand or power drilling tools are suitable forproviding penetrations.Fixing of bottom platesThe lateral force effects due to wind and earthquakes are resistedby bracing walls results in two separate methods of action onbracing elements. The first action is an in-plane sliding force transferred to the bottom plate. Sufficient fixings of the bottom plateto the sub-floor/slab must be designed to resist this in-plane‘shear’ force.The second action induces rotation or overturning effects whichtie rods extending from the top plate to the sub-floor and locatedat each end of bracing wall provide excellent resistance. For bracing elements requiring lower resistance, nominal connection ofthe bottom plate to the sub-floor/slab can overcome these overturning forces. Nominal fixings (minimum fixings) are defined inclause 9.5 of AS 1684.2 – 2021, but for bottom plates the requirements for nominal fixing is shown below.1. Bottom plate fixing up to 3.4 kN/m systemsNo additional bottom plate fixing other than nominal bottomplate fixing as specified in AS 1684 is required for bracing systemswith resistance less than 3.4 kN/m. However, if the 3.4 kN/m system is used on both sides of a frame to double the bracing capacity in that section of wall, then the bottom plate fixing will need tobe upgraded to be equivalent for a 6.4 kN/m system.2. Bottom plate fixing for 5.3, 6.0 and 6.4 kN/m systemsThe minimum fixing requirement for 5.3, 6.0 and 6.4 kN/m bracing capacity systems is 13 kN tie down every 1200 mm along thebottom plate or equivalent.A looped 30 mm x 1 mm width galvanised looped strap as shownabove is equivalent to 13 kN tie down.Wall height (mm) Multiplier2400 1.122700 1.003000 0.903300 0.803600 0.753900 0.704200 0.64WindclassificationConcrete slabsubfloorBottom plates≤ 38 mm tojoistsBottom plates38 to 50 mm tojoistsN1, N2, N3,N4 and C1,C2 and C375 mm masonrynails, screws orbolts and 1200mm max centres2/3.05Ø x 75mm at a max of600 mmcentres2/3.05Ø x 90mm at a max of600 mmcentresFloor joist1 Fastener intop of plateBottom plate2 fastener inface of plate Galvanised steel strap 30 mm x 1 mm minimum,fixed to bottom plate each sideof floor joist by 3 off 2.8 mm x 30 mmstructural clouts or equivalentF22 SmartBrace Design Guide 5 June 20233. Bolt fixing of bottom platesThe tie down capacity of some bolts through a range of timberjoint strengths are presented below. If the bolts are used in concrete slabs they must be appropriately embedded. For lower capacity bolted joints the resistance can be obtained by reducing thespacing of the bolts.Uplift CapacitiesStorage and handlingCorrect storage and handling of F22 SmartBrace is essential toensure problem free installation and to guarantee bracing resistance capacities for each panel as specified in this Design Guide.1. Store SmartBrace panels horizontally on squared bearersof even height2. Should packs be stacked on top of each other, bearersshould be aligned vertically3. Bearer spacing is to be as per the table below.4. SmartBrace should be stored protected from direct exposure to the weather in a well ventilated area5. SmartBrace panels should not be stored in direct contactwith the ground6. If the panels are to be moved by mechanical lifting equipment such as fork lifts, the bearers must be of sufficientheight to allow forks to slide under the full pack withoutcausing damage to panels.Joist strength group J2 J3 J4 JD4 JD5 JD6Bolt diameter (mm) Capacity in kN10 18 18 18 15 12 912 27 27 26 20 16 1216 50 50 46 35 28 21TensionBottom plate connection to floor substrate as per AS 1684.
