Hoor Joist Span Tables 10 psf Dead Load and 20 p f Live Load <br /> Complies with 2009&2012 International Building Code(IBC) <br /> Allowable Floor Joist Span Table Notes <br /> 1. Spans are based on continuous support of compression flange over the full length of the joist. <br /> 2. Spans are based on tension flange laterally braced at maximum spacing of 8'-0". <br /> 3. For two equal spans,the listed span is the distance from either end to the center support,with the joist continuous over the center support. <br /> 4. Joists must be braced against rotation at all supports. <br /> 5. End shear and web crippling capacity have not been reduced for punchouts. <br /> 6. End web crippling check is based on 3'A"end bearing.Where listed allowable spans are followed bye",web stiffeners are required at end supports. <br /> 7. Interior support not checked for combined bending and web crippling.Web stiffeners are required at interior supports. <br /> 8. Shear capacity at interior support has been reduced for the presence of punchouts adjacent to the supports.Combined bending and shear check is based on <br /> unreinforced web in accordance with section C3.3.1 of AISI S100. span(rq Minimum Number of Rows <br /> 9. Total load deflection limited to L/240.Live load deflection limit is as noted. up to 16 ft. 1 row at mid-span <br /> 10. Alternate span live loading has been considered for two equal span conditions. ------------ <br /> 11. 11.See page 2 for additional table notes. 16 IL to 24 ft. 2 rows at 1/3 points <br /> 24 ft.to 32 rt. 3 rows at 1/4 points <br /> Bridging Recommendations <br /> Bracing components shall be designed in accordance with section D3 of AISI S100. The minimum number of rows required is shown in the table.Additional rows of <br /> bridging may be required by design. <br /> 10 psf Dead Load and 20 psf Live Load <br /> ( L1360 Live Load Deflection L?480 Live Load Deflection <br /> Section j F, Single Span Two Equal Spans I Single Span Two Equal Spans <br /> I Spacing fin) Spacing(in) Spacing(In) Spacing(in) <br /> • <br /> (lisi)l 12 tp=46 24 12 I 16 I 24 12 I 16 1 24 12 16 24 <br /> 6008162-33 33 14 6 + 12 7 e 10'3"a 14'6' 12'7" 10'1" 14'4" 12'7"a 10'3"a 14'6" 12 7" i 10'1" <br /> 600S200-33 33 15'6' 13 5"e ; 10'11"a 15'6 13'3" 10'5" 15'0" I 13'5"e bile 15'6" 13 3" 1 10'5" <br /> 600S162-43 33 17'2" 15'6" 12'8" 17'11 15'8"— 12 8" 15'7" ; 14'2" 12'5" 17'6" 15'6" 12'8" <br /> 600S200-43 j 33 18'0" 'I 16'0" J 13'1" 18'6" 16'0" 13'1" 16'5" 1 14'11" 13'0" 18'5" j 16'0" 13'1" <br /> 600S250-43 33 18'11" 16'5" 13'5"e 19'0" , 16'5" I 13'5" 17'2" 15'7" 13'5"e 19'0" 16'5" 13'5" <br /> 600S250-54 50 20'3" 18'5" 16'1" 22'9" 20'8" _ <br /> 16 5" 1 G'9" 15 2" 13'3" 18 9" j i 1 14 11" <br /> 600S162-54 50 18 5 16 9" 14 7" 20'8' 18'9' <br /> 17'3" 17'7" 16'0" 14'0" 19 9" 17 11' 15 8" <br /> 600S200-54 50 19 4 17 7" 15 4" 21'9'�• 18 9 17'10" 18'5" 1G 9" 14'8" 20'8" !
