JOISTINFORMATIONJOIST PROFILESSTANDARD PROFILESPARALLEL CHORDAll standard profile joists are availablewith either under-slung or square ends.LH-Series and DLH-Series joists areavailable with single pitched or doublepitched top chords. The depth indicatedin joist designation is determined by thedepth of single pitched joists at thecenter of span and at ridge center line ofdouble pitched joists. When top chordslope exceeds 1/8":12", total and livetop chord uniform loads must beprovided. All standard profile joists willbe furnished with standard SJI camberas indicated in SJI Table 103.6-1,unless specified otherwise in contractdocuments.SPECIAL PROFILESSpecial profiles shown are alsoavailable. Special profile joists areavailable with either under-slung orsquare ends. Contract documents mustinclude all dimensions as indicatedalong with all loading requirements. Allspecial profile joists will be furnishedwith no camber unless specifiedotherwise in contract documents.Scissor and barrel profile joists willinduce horizontal forces due todeflection, and need to be considered inbuilding design by a designprofessional.9

LOADTop and bottom chords of joists, including KCS-Series, are notdesigned for localized bending from concentrated loads.Concentrated loads must be applied at joist panel points or fieldinstalled web members must be utilized at no cost to NMBS. NMBScan provide specially designed joists with the capability of supportingconcentrated loads without the added members if this requirementand the exact locations and magnitudes of the concentrated loads areclearly shown in the contract documents. Also, NMBS can considerthe worst case for both shear and bending moment for movingconcentrated loads with no specific locations.
