Structural use of timber. Recommendations for the calculation basis for span tables - Joists for flat roofs Ingestion-build-256245 9 CertificateBS 5268 7. 2: 1989 recommends a calculation basis for the permissible clear span for joists for flat roofs and roofs with a slope of up to 10 degrees. The recommendations apply to joists 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. The method of calculation makes no allowance for any contribution of the roof decking to the load resistance
