Recommendations for the calculation basis for span tables - Joists for flat roofsBS 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.
