Floor loading applied includes an allowance for:  \n• Floor mass not exceeding 40 kg/m2  \n• Live load of up to 1.5 kPa/1.8 kN, for use in domestic houses.  \nFor other situations, such as decks, balconies, tiled areas and apartment floors, our free designIT® software should be used for specification where alternate loading conditions may be applied.  \nWind Loading  \n• N3 design wind classification used  \nunless noted otherwise For design wind classification N4 or greater and cyclonic wind regions designIT should be used for member sizing.  \nMember Specification  \nIn selecting an appropriate beam size, specifiers should also consider the applicability of design deflection limits for the beams intended use.  \nInstallation  \nThe hySPAN range specified within this brochure can be installed in accordance with traditionally recognised framing practice as described in AS1684 and other installation details contained and referenced within this brochure.  \nFor on-site, technical and product support, including assistance in sizing freecall 􀀋1800 808 131  \nFor specific support and tie-down calculation, refer AS1684 or consult designIT where reactions are provided for all members for specification with typical connection details in AS1684 and other proprietary fastening systems.  \nSub Floor Applications  \nUnder normal conditions where adequate ventilation and clearance are provided, hySPAN may be safely used for sub-floor applications without the likelihood of decay.  \nDurability  \nhySPAN is not suitable for weather exposed applications unless suitably preservative treated. For guidance on treatment requirements please consult Carter Holt Harvey's brochure, ‘Use of hySPAN and hyJOIST for weather exposed applications’ along with useful industry reference manuals such as AS1684.2-2010 Appendix B and the FWPA-Timber service life design guide.  \ndesignIT Software  \nFor optimised design using the full range of hySPAN sizes, our designIT software can be downloaded from: [www.chhsoftware.com/designIT](www.chhsoftware.com/designIT)  \nMore online.
