SpaceJoist: Residential Floor Span Charts 4 Up to 12" may be field-trimmed from each end of the SpaceJoist TE truss. Contact your SpaceJoist representative or Engineering Department prior to any additional trimming. Span charts reflect the benefit of composite action afforded by a glued-nailed or glued-screwed connection of the sheathing to the top chord of the truss. Consult SpaceJoist for appropriate spans if a nailed-only or screwed-only connection is to be utilized. Span dimensions are out-to-out at bearing supports. Minimum required bearing length is 1-3/4". Span charts are for the uniformly loaded conditions specified in the heading of each chart. For SpaceJoist trusses supporting concentrated (point) loads, cantilevered end conditions, or other special loading conditions, contact your SpaceJoist representative. Some spans may require top chord supports and/or web stiffeners. Contact SpaceJoist engineering for required reinforcements. * Span Charts for additional loadings are available from your SpaceJoist representative. www.spacejoist.com Maximum Spans: 40-10-5 420 Series Depth Deflection 24" O.C. 19.2" O.C. 16" O.C. 12" O.C. 9¼" L/480 14'4" 15'6" 16'6" 18'2" L/360 15'10" 17'1" 18'2" 19'11" 11¼" L/480 16'0" 18'8" 19'10" 21'10" L/360 16'0" 20'0" 21'10" 24'1" 11 7/8" L/480 16'0" 19'6" 20'8" 22'10" L/360 16'0" 20'0" 22'10" 25'3" 14" L/480 20'3" 22'1" 23'8" 26'0" L/360 20'3" 24'0" 26'0" 28'0" 16" L/480 22'0" 24'11" 26'7" 29'3" L/360 22'0" 26'0" 29'3" 32'0" Maximum Spans: 40-10-5 320 Series Depth Deflection 24" O.C. 19.2" O.C. 16" O.C. 12" O.C. 9¼" L/480 12'9" 13'10" 14'8" 16'1" L/360 14'1" 15'3" 16'1" 17'11" 11¼" L/480 15'3" 16'7" 17'8" 19'6" L/360 16'0" 18'4" 19'7" 21'6" 11 7/8" L/480 16'0" 17'4" 18'6" 20'4" L/360 16'0" 19'2" 20'5" 22'6" 14" L/480 18'3" 19'9" 20'11" 23'3" L/360 18'6" 20'8" 23'3" 25'7" 16" L/480 18'6" 22'2" 23'8" 26'2" L/360 18'6" 22'11" 26'2" 28'9"
