TJI® JOIST RESIDENTIAL FLOOR SPAN CHARTS 40 PSF LIVE LOAD, 10 PSF DEAD LOAD (Example: Single layer glue-nailed wood sheathing and direct applied ceiling) I./360 LIVE LOAD DEFLECTION (Code Minimum) I./480 LIVE LOAD DEFLECTION 40 PSF LIVE LOAD, 22 PSF DEAD LOAD (Example: Single layer glue-nailed wood sheathing with 11/='' lightweight concrete and direct applied ceiling) L/360 LIVE LOAD DEFLECTION (Code Minimum) ' I./480 LIVE LOAD DEFLECTION NOTE: Although the "L/480 Live Load Deffecllen" charts will usuall~ provide berber floor performance than the "L J360 Live Loart Deflection" charts, the resuitlng porto msnce still may not be adeduate for your ~2roject, See page 3 for ' A WORLD ABOUT FLOOR PERFORMANCE," or contact ye r Tr s Joist MacMillan representative for assistance. GENERAL NOTES: 1. Span charts assume composite action with single layer of the appropriate span rated glue-nailed wood sheathing for deflection only. Spans shall be reduced 5" where sheathing panels are nailed only. 2. Spans are based on clear distance between Supports, unlfarmly loaded ioists, and incIude allowable increases for repetitive USe rTlem bors. 3. For loading condit{oRs not shown, refer to allowable uniform toad tables on page 14. ~4, Spans shown reflect the most restrictive of simple span or multiple span applications, 5. Long term deflection under dead load which includes the effect O~ creep, common to all wood members, has not been considered for any of the above application$.,~spans reflect initiaI dead load deflection exceeding 0.33," which may be unacceptable. For additional information contact youFTr','Ts-V'aist MacMillan representative. WEB STIFFENER REQUIREMENTS 6. End Bearings: Web stiffeners (see detail "K" on page 7) are nat required at end bearings of TJI® floor joists listed in this guide except in hangers when the sides of the hanger do not laterally support the TJI® joist top flange. (See detail "H1" on page 7). 7, Intermediate Bearings: At intermediate supports where the joist~ are continuous span, web stiffeners are required only if the intermediate bearing width is less than 5V4" and the span on either side of the fntermediate bearin9 is greater than the spans shown in ~he following ohart: WEB STIFFENERS NOT REQUIRED ,, WEB STIFFENERS NOT REQUIRED ~.=-__l Not Reg,u red Not Required 24 -~ ,,, 19'~" ,,,, 31'-3' I 2~'4" I 8 When us ng IUT9 hangers w h his aae/sgacTng oond~ ion he max mum ~ st span s 13'-9," Page 5
