SPAN TABLES - These span tables have been developed in good faith, with the assistance of Mr.Peter Falvey B.E., M.I.E.Aust., C.P.Eng., R.P.E.Q. Provides the building industry with procedures that can be used to determine building practice to design or check Construction details, determine member sizes and bracing and fixing requirements for timber framed construction in Non-Cyclonic areas (N1 N4). Maximum deck joist span is based on supporting a maximum decking mass of 20 kg/m2, imposed point load of 1.8 kN, imposed distributed loading of 2 kPa and 450 mm joist spacing. The natural frequencies of the roof trusses are computed from a dynamic analysis. They are simply called up or calculated based on members framing into them. Rafter spans are measured as the distance between points of support along the length of the rafter and NOT as the horizontal projection of this distance. WOODexpress- An easy and versatile program for designing and dimensioning timber components, and timber roofs according to Eurocode 5 (EC5). It can also be cut, nailed, drilled and screwed with ordinary hand tools and is planer gauged for more accurate marking and jointing. Notes: LOSP (Light Organic Solvent-Borne Preservative). Span is the face-to-face distance between points capable of giving full support to structural members or assemblies. But there are differences between the two Standards that users must be aware of that places limitations on the simplified version. Pine was chosen as a plantation species due to its robustness, excellent growth and versatility of its timber. Study Resources.
