Span tab les pack: E uro c ode 5 & BS 5268 calc u lations Also available separately, both editions of Span tables contain section sizes and spans for solid timber members in floors, ceilings and roofs (excluding trussed rafter roofs) for dwellings. The calculations apply to buildings up to three storeys in height above ground level. Span tables were originally included in the England and Wales Building Regulations, Approved Document A: Structure and subsequently revised by TRADA. Tables are included for domestic floor joists, ceiling joists and binders, and rafters and purlins supporting rafters for traditional pitched roofs. Calculations are also given for “canted” purlins supporting roof sheeting or cladding, and for flat roof joists. The tables cover softwood species and grade combinations which satisfy strength classes C16 and C24. This pack includes the 2nd edition with calculations to BS 5268 plus the new 3rd edition which conforms to the current British Standard supported by the British Standards Institution, BS EN 1995: Eurocode 5, which came into effect in April 2010.
timbersizer Pro EC5 & timber conne c tions Pro EC5 timberconnectionsPro EC5 is a design tool which calculates the resistance to lateral and axial loads of timber-to-timber and steel-to-timber connections made with nails, wood screws, bolts or dowels inserted at right-angles to the grain. Design loads are calculated to Eurocode 5. Coach screw connections for two-member joints are also included. Eurocode 5 timberconnectionsPro is available on a subscription basis only, with a reduction for both modules together. timbersizerPro EC5 is a time saving online tool for architects, builders, engineers and other construction professionals. It will help ensure their designs meet the requirements of Eurocode 5 (EC5), which replaced British Standard 5268 in April 2010.

Based on TRADA calculations, timbersizer EC5 covers all domestic structural timber members: • Joists for domestic floors, ceilings or flat roofs • Binders supporting ceiling joists • Rafters • Purlins supporting rafters, sheeting or decking. timbersizerPro EC5 incorporates additional functionality for professional designers and generates custom reports in PDF format for records and Building Control purposes. Subscribers can further refine their design using advanced controls to adjust more parameters, for example: • The strength class • Bearing length • Breadth or cross section depth • Distributed imposed load • Concentrated imposed load.
