Description

Long recognised as a key resource in timber specification and building, this publication has now been revised and updated to comply with Eurocode 5. EC5 Span tables is:
- The definitive reference guide for designers, specifiers and builders
- Researched and written by TRADA, experts on timber
- Designed to supplement the England and Wales Approved Documents
- Applicable to timber design in other UK jurisdictions.

New features in this 3rd edition include:
- Timber specifications to BS EN 1912
- Loads from Eurocode 1 including the National Annex
- New snow loads for the UK.

Eurocode 5 span tables contains 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. Frequently asked questions are addressed in the notes alongside the tables.
