Structural use of timber. Recommendations for the calculation basis for span tables - Domestic rafters Ingestion-build-141043 Improving phaseBS 5268 7. 5: 1990 recommends a calculation basis for the permissible clear span for rafters for roofs with a slope from15 to 45. The recommendations apply to rafters at a maximum spacing of 610 mm centre to centre, this being the maximum spacing for which the load sharing assumption may be adopted as described in BS 5268 2.
