TerminologySpanSpacinga) The beam is not notched or partiallycut through at internal supportpoints and,For the purpose of using these tables,span may be interpreted as the cleardistance between supports measuredalong the beam. Single Span Beams arebeams supported at two points only.Continuous Span Beams are beamssupported at three or more points alongtheir length.b) If the spans are not equal, the largestspan is not greater that twice thesmallest adjacent span.However if either of the above conditionsare not met, use the single spantables for the purpose of obtainingthe appropriate size.Continuous span values given in thetables should only be used where:Tables, such as those for rafters,floor joists and ceiling joists requirethe spacing of members to be knownor selected in order to obtain therequired size for a given span. Spacingshould be interpreted as the centreto centre distance between adjacentparallel members.SPANSINGLE SPAN BEAMSPSPSPAN L 2SPAN L1ACCONTINUOUS SPAN BEAMACINGINGLoad WidthsRoof load width (RLW) and Floor load width (FLW) can be determined from AS1684, or from the images below.DETERMINATION OF FLOOR LOAD WIDTHFLOORJOISTSBEARERAXBEARER ‘A’FLOOR LOAD WIDTH ‘FLW’Y2Y ZFLW 2ZFLW 2FLW X BYCBEARER ‘B’ZBEARER ‘C’DETERMINATION OF ROOF LOAD WIDTHRLW SUPPORTSUPPORTSUPPORTBEARER RLW BEARERBEARERCONVENTIONAL ROOFCOUPLED, STRUTTED RIDGERLW CATHEDRAL ROOF RLWSUPPORTSUPPORTTRUSSED ROOFR2R 1 2R2R1BEARERCONVENTIONAL ROOFCOUPLED, UNSTRUTTED RIDGERLW BEARERCATHEDRAL ROOFThese diagrams may also be used todetermine roof load width for floor joistssupporting load bearing walls and lintelsin lower storey load bearing walls.For on-site technical and product support, including assistance in sizing freecall 1800808 1313

With ten sizesranging in depth from 200 to 400 mm,hyJOIST provide the perfect long spansolution for mid floor joist design, andallows for concealed services within thedepth of the floor.

Span For the purpose of using these tables, span may be interpreted as the clear distance between supports measured along the beam. Single Span Beams are beams supported at two points only. Continuous Span Beams are beams supported at three or more points along their length. Continuous span values given in the tables should only be used where:File Size: 494KB
