Span Tables for Domestic Floor Joists (to BS 5268-7.1), Span Tables for Ceiling Joists (to BS 5268-7.3), Span Tables for Flat Roof Joists (to BS 5268-7.2), Span Tables for Purlin Supporting Rafters (to BS 5268-7.6). These span tables have been prepared for a range of flooring and roofing applications in non-cyclonic wind regions using Boxspan® steel beams and brackets produced by Spantec Systems Pty Ltd. 2. ... Span –the distance me asured along thecentreline ofa member between Tables 1 and 2 in this chapter are derived from the TRADA Technology Ltd. ‘Eurocode 5 span Tables for solid timber members in floors, ceilings and roofs for dwellings (3rd edition)’. Imposed load not exceeding 1.5 kN/m2. Table R502.3.1(1) shall be used to determine the maximum allowable span of floor joists that support sleeping areas and attics that are accessed by means of a fixed stairway in accordance with Section R311.7 provided that the design live load does not exceed 30 pounds per square foot (1.44 kPa) and the design dead load does not exceed 20 pounds per square foot (0.96 kPa). Partitions should be fixed through the floor decking into the joist(s) beneath. Solid timber joist sizes are provided in the BS 8103-3 span tables. Imposed loads of 0.75 kN/m² for maintenance and snow load are applicable where there is no permanent access (no fixed ladder or staircase) and most areas where the altitude does not exceed 100 metres (refer to BS 6399-3), Imposed loads of 1 kN/m² for maintenance and snow load are applicable where there is no permanent access (no fixed ladder or staircase) and most areas where the altitude exceeds 100 metres but does not exceed 200 metres, but excluding parts of Scotland, Pennines, North East England (refer to BS 6399-3), Imposed loads of 1.5 kN/m² are applicable where there is permanent access to the flat roof.

Note: Our floor joist span tables are based on loadings given in the newer, amended version of BS 6399-1. Exceptional floor performance from a wide fixing surface makes flooring easy, controls shrinkage This should be compared to the table. Partitions may be directly supported by one or two additional joists. use the centre three columns from Tables 1 and 2. Adherence to the approach outlined in a Technical Guidance Document is regarded, as evidence of compliance with the requirements of the relevant part of the Building Regulations. You need to measure the complete span of your floor joists, together with the distance between them (the ‘centres’) and the size of the timbers. Its span capability and wide timber flanges make it the more desirable alternative to all steel systems. load-bearing intermediate walls, dramatically cutting overall building costs. Click on a span to generate a full calculation (you can adjust the exact span).

SPAN TABLES Span tables can be used to determine the size of a timber member of a particular strength class required for a given span. Other span tables are based on the guidance given in BS 5268-7.1 which is a uniformly distributed load of 1.5kN/m² for spans greater than 2400 mm and 3.6 kN load per metre width of floor for spans less than 2400 mm to ensure that very small joist sizes do not result from the calculations for smaller spans. Ap 2019 Design Notes 1. These span tables are the equivalent of other industry-standard span tables and are calculated to the same standards. The following table gives details of allowable spans and spacing between joists for the most common timber sizes used in floor construction. * Two additional joists required The Approved Documents provide guidance on ways to meet the building regulations. Service class 1 or 2. This Design Notes section shall be read in conjunction with Boxspan Residential Span Tables – Non Cyclonic Areas publication.
