A companion Supplement to Span Tables for Joists and Rafters, Design Values for Joists and Rafters tabulates allowable bending (Fb) and modulus of elasticity (E) design values for visually graded and mechanically graded dimension lumber. Lumber design values used to calculate maximum horizontal spans include modulus of elasticity (E), bending strength (F b), and shear strength (F v).Bearing strength in compression perpendicular to grain (F cp) is used to determine the minimum required bearing length at each end of joists and rafters.Calculated spans incorporate design value adjustments appropriate for repetitive-member use … Find the column for your dead load and spacing, and the row for your timber size to find the permissible clear span in metres. �#:"M@' }�N��SLj� w��BlϘ���� y��4#2��8��j�-u'�u���wH# �H�ת�*�#ڈ���|�EQ��!����S>��TK�|��7�V���z��]�V]����MX��a��l|m��#��_�:I1�+�G;�4�-}�1��1�ݎڃ�Q�{e�U#I]+[H�� It is simple to use, yet flexible 2013-05-16T15:22:06-05:00 (the tables permit a bearing length of up to 3.5 inches, but since 1.5 is probably the worst case that you'll … If there is a change to lumber design values in 2012, affected AWC design standards and design aids would be amended accordingly. Note: Our floor joist span tables are based on loadings given in the newer, amended version of BS 6399-1. (47 pages, 331 KB PDF). You can also use the Wood Beam Calculator from the American Wood Council website to determine maximum rafter and joist lengths. the American Wood Council; concentrated loads and uplift loads caused by wind were not considered. The dead loads shown at the top of span table above do not include the self weight of the joists, however, the joist self weights are included (in addition to the dead loads) in the calculations used to determine permissble clear spans.

Table 9.1 in Span Tables for Joists and Rafters (Figure 5) gives a required compression value of 237 psi for a span of 16 feet and bearing length of 1.5 inches.

Joists supporting additional loads should be calculated by a competent person. This means that some values are slightly more conservative than span tables from other sources if those do not include the amended guidance. The user enters the member geometry, adds Joist spans up to 2.5m - no strutting required, Joist spans 2.5m to 4.5m - provide strutting at mid-span, Joist spans over 4.5m - provide 2 rows of strutting at third span positions.
