SmartForm 11.7 - “F” gradetimber comparisonLVL is an engineered mber product whose characteriscstrength properes are derived by in-grade tesng to AS/NZS4063. “F”” grades are assigned aer visual grading of the solidmber to the appropriate standards.There is no direct link between “F” graded mber and in-gradetested mber.Notwithstanding the above, SmartForm 11.7 may be used tosafely substute “F” graded material up to and including F8.Design capacies for the table are based upon the following criteria:SmartForm 11.7 Section propertiesSmartForm sizeD x B mmSelf weightkg/mRigidity EIx 10 9 Nmm 2BendingΦM kNm• Capacity reducon factor Φ = 0.85 (Primary Structural Elements other than houses table 2.5 AS 1720.1)• k 1 = 0.94 (Duraon of 5 days) AS1720.1• Full lateral restraintDesign CapacityShearΦV kN95 x 45 2.4 37.6 2.2 7.595 x 63 3.4 52.7 3.1 10.5130 x 75 5.6 160.7 6.8 17.1150 x 75 6.4 246.8 9.1 19.8SmartForm 11.7 Product MarkingFormwork Design ProcessThe design of formwork always starts with defining the qualityof the finished concrete surface. This is usually communicatedthrough the project documents. Surface quality is effected bythe extent to which the formwork components deflect underthe applied loadings. Physical quality and tolerances, detailedin AS 3610 tables 3.3.1 and 3.4.2 guide the formwork designerin the selecon of formface material and deflecon limits forthe framing members for soffits and wall forms. The tablesinclude the deflecon criteria for the most common classes offinish, namely: Class 3 - Maximum of 3 mm or span/270CONVENTIONAL SOFFIT FORMWORK FOR SLABSFormworkSpan tables for alternave deflecon limits are available bycontacng the SmartData Customer HelpLine on 1300 668 690or at smartdata@lling.com.auThe design aids in this design guide are confined to the selec-on of SmartForm 11.7 LVL members which ensure that theformwork provides the strength and rigidity necessary to meetboth structural safety and surface quality requirements. Structuralsafety is limited to the selecon of individual structuralcomponents subject to normal concrete pressures. This designguide does NOT address the structural safety of the systemthat may be subject to a wide range of abnormal and accidentalloads. Methods for developing lateral restraint, providingadequate support as well as the overall stability of thestructure are outside the scope of this publicaon.BearerPropJoistThe members in this table have been designed based upon theaddion of the “Global load factor for primary member” introducedinto AS 3610 - 1995 with Amendment 1 - 2003.JoistspanJoistspanProp spacingand BearerspanProp spacingand BearerspanFor horizontal members such as bearers and joists for soffits,both the joists and bearers have been considered primarymembers.

Minimum bearing length = 45 mm atend supports. Subscript values indicateaddional bearing length requiredabove the minimum of 45 mmto achieve the stated span2. Spans in tables have been designed asper secon 4 of AS 3610-1995, includingAmendment 1:2003 for all stage 1,2 and 3 loadings. This allows for a 4.0KPa imposed load due to stackedmaterial as a stage 3 loading. This loadis considered to be addional to otherlive loads. If the project designer applieslimitaons to restrict these materialloads to a lesser amount (as specifiedin Clause 2.3(b) of AS 3610 -1995), then larger spans will beachieved.3. Since the finish quality is dependentupon a number of factors includingthe formface used and the accuracy ofthe setup, a class 3 finish cannot beguaranteed.4. For mulple spans, the design hasassumed the most conservave of 2and 3 spans and that all spans areessenally equal.5. The design has assumed that the joistsare connually restrained by thesheeng and the bearers are restrainedby the joists.6. The design tables are only suitable forhorizontal forms. For angled soffits,consult a formwork designer.Joist sizeDxB (mm)95x4595x63130x75150x75Joist sizeDxB (mm)95x4595x63130x75150x75Slab depthJoists spacing (mm)(mm) 225 300 400 450 480 600100 1900 1700 1500 1500 1400 1300150 1800 1600 1500 1400 1400 1300200 1700 1500 1400 1300 1300 1200300 1600 1400 1300 1200 1200 1100400 1500 1300 1200 1100 1100 1000600 1300 1200 1100 1000 1000 NS1000 1100 1000 NS NS NS NS100 2100 1900 1700 1700 1600 1500150 2000 1800 1600 1600 1500 1400200 1900 1700 1600 1500 1500 1400300 1800 1600 1400 1400 1400 1300400 1600 1500 1300 1300 1300 1200600 1500 1300 1200 1200 1100 11001000 1300 1200 1100 1000 1000 NS100 3100 2800 2500 2400 2400 2200150 2900 2600 2400 2300 2300 2100200 2800 2500 2300 2200 2100 2000300 2600 2300 2100 2000 2000 1800400 2400 2200 2000 1900 1900 1700600 2200 2000 1800 1700 1700 16001000 1900 1700 1600 1500 1500 1300100 3600 3200 2900 2800 2800 2600150 3400 3100 2800 2700 2600 2400200 3200 2900 2600 2500 2500 2300300 3000 2700 2400 2300 2300 2100400 2800 2500 2300 2200 2200 2000600 2500 2300 2100 2000 1900 18001000 2200 2000 1800 1700 1700 1600Continuous SpansSlab depthJoists spacing (mm)(mm) 225 300 400 450 480 600100 2300 2100 1900 1700 1700 1500150 2200 2000 1700 1600 1600 1400200 2100 1900 1600 1500 1500 1300300 1900 1700 1500 1400 1300 1100400 1800 1600 1300 1200 1200 1000600 1600 1400 1200 1100 1000 NS1000 1300 1100 NS NS NS NS100 2600 2400 2200 2100 2000 1800150 2500 2200 2000 1900 1900 1600200 2400 2100 1900 1800 1800 1500300 2200 2000 1800 1600 1600 1400400 2000 1900 1600 1500 1400 1300600 1900 1700 1400 1300 1300 11001000 1600 1300 1100 1000 1000 NS100 3800 3500 3100 3000 2900 2600150 3600 3300 3000 2800 2800 2400200 3400 3100 2800 2700 2600 2300300 3200 2900 2600 2400 2300 2100400 3000 2700 2400 2200 2100 1900600 2700 2400 2100 1900 1900 16001000 2300 2000 1700 1600 1500 1300100 4400 4000 3600 3500 3400 3000150 4200 3800 3400 3300 3100 2800200 4000 3600 3300 3100 3000 2600300 3700 3300 3000 2800 2700 2400400 3500 3100 2700 2500 2500 2200600 3100 2800 2400 2200 2100 19001000 2700 2300 1900 1800 1700 1500SmartForm 11.7 Design Guide 3 Edition 2 Jan 2012
