SPAN TABLESFLOOR LOAD TABLEHow to Use1. Calculate total factored load and specified total / live loads, see conversion tableon the next page for assistance.2. Look down the column of the appropriate span (values between tabulated spanscan be interpolated).3. Scan the table to find a row where the tabulated resistance load and specifiedtotal /live loads are greater than or equal to the calculated required loads.4. Select the TotalJoist.See example on page 17 for more guidance.FLOOR LOAD TABLE 46134269212108215NOTES Tables are based on: Strength Allowable shear strength through solid web. Check shearstrength through hole if close to support, see page 3. Allowable bending strength Bearing capacity NOT considered. Designer must checkbearing capacity separately, see page 16. Deflection limitations of: L/480 based on live load L/240 based on total load Uniformly distributed loads Simply supported joists For deflection limit other than L/480, multiply tabulated “LiveLoad” value by the factor below: For L/600, multiply by 0.80 For L/360, multiply by 1.33 For L/240, multiply by 2.00 For fire rated assemblies, refer to approvals sectioniSPAN Systems LP70 Brentwood Drive, Princeton, Ontario, Canada N0J 1V0T 519-458-4222 F 519-458-4460 E info@ispansystems.com iSPANsystems.com15

SPAN TABLESDESIGN EXAMPLESelect a joist for a 22' span, residential loading, with a maximum spacing of 19.2" o.c. and without additionaltopping on the floor. Design floor based on a 15 psf dead load (including self-weight of the floor system).SOLUTIONOption 1Select joist using Span Tables1. Use the Floor Span Table for 40 psf live load found on page 4.2. Scan down column for 15 psf dead load and 19.2" spacing.3. Select 14-i-2 at 19.2" o.c.:Maximum Span 24' 0" 22'OKOption 2Select joist using Span Tables1. Determine total load: 15 psf 40 psf 55 psf2. Determine specified total and live loads on one joist(see Conversion Table on page 16 for joist spacing of 19.2"):a. For specified live load of 40 psf, joist load is 64 plf,b. For specified total load of 55 psf, joist load is 88 plf.3. Using Floor Load Table on page 15, scan column for 22' for a row where total factored load andspecified total/live loads exceed values calculated above.4.
