Final design confirmation and for further design options including continuous spans or non-uniformly loaded joists please refer to the Dindas Design Guide or reach out to us at any of our state locations or request information through. These calculation results are only to be used as a handy guide (not for construction) when designing your project joist spans. This can be a solid bottom edge bearing (like a wall) or face fixed metal hanger bearing conditions (35mm) or greater have been included in the design. * Joists with a Max.Centre spacing of 600mm or less = 22mm min

Total Load deflection is limited to L/240. Live Load deflection is limited to L/480 or L/360 as indicated in the tables above. The shortest span shall not be less than 40 of the longest span. Multiple spans are based on the longest span. * Joists with a Max.Centre spacing of 450mm or less = 19mm min Multiple span lengths shown require adequate lateral bracing of bottom edge of LVL. Joist Centres is 300mm then it can only be used at any joist centres equal to or less than 300mm centres.įlooring thickness must be checked before installation to ensure it can span the intended Max. Centres” is 600mm, the joist can be used at the lower nominated spacings ie 300mm, 400mm, 480mm, and 600mm centres. Centres are the maximum centres that this joist can be installed at. The Class 1 classification includes two sub-classifications: Class 1a and Class 1b For example what size lvl beam for a 20 foot span, as per general thumb. In these situations, they must be separated by a wall that has fire-resisting and sound insulation properties. Look no further, this online calculator will help you with your general timber. They can also be horizontally attached to other Class 1 buildings such as terrace houses, rowhouses, or townhouses.
