Floor Joist Span—Residential Sleeping Areas. 2012 IRC Table R502.3.1(1) - Floor Joist Spans for Common Lumber Species. Residential Sleeping Areas, Live Load ...The spans are based on simple-span joists. The minimum bearing length is 1 ½”, spans values in bold indicate that web stiffeners are required at the OSB end panel. The maximum span is measured o.c. of bearings and is based on uniformly loaded joists. Dead load deflection is limited to L/360 and total load deflection is limited to L/240. 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. (the tables permit a bearing length of up to 3.5 inches, but since 1.5 is probably the worst case that you’ll encounter for joist or rafter bearing, it’s a safe value.) Click on a span to generate a full calculation (you can adjust the exact span). This span table is to the format and methodology given in BS 5268-7.1. These spans were calculated using our floor joist calculation engine. These span tables are the equivalent of other industry-standard span tables and are calculated to the same standards.
