Structural use of timber. Recommendations for the calculation basis for span tables - Purlins supporting rafters Ingestion-build-225643 BS EN ISO 2808:2019 supersedesBS 5268 7. 6: 1990 recommends a calculation basis for the permissible clear span of purlins used in traditional pitched roof construction, i. e. not including trussed rafter roofs. The method of calculation is for purlins formed from solid timber and supported by external or internal walls or by purlin struts. The major axis of the purlin is perpendicular to the rafter slope; other orientations of the purlin are not covered by this Section of BS 5268.
