　　SpanLength

　　Thelongertheunsupporteddistancebetweensupports,thegreaterthestructuraldemandplacedonthebeam.

　　Long-spanapplicationsgenerallyrequire:

　　*Greaterbeamdepth

　　*Higherstiffnessgrades

　　*Enhancedbendingresistance

　　Increasingbeamdepthisoftenthemosteffectivewaytoimprovestructuralperformancewithoutsignificantlyincreasingweight.

　　StructuralLoadRequirements

　　Everybeamcarriesdifferenttypesofloads.

　　Forexample:

　　*Residentialfloorsystemssupportfurniture,occupants,andinteriorfinishes.

　　*Roofstructuresmustresistdeadloads,windloads,andinmanyregions,snowloads.

　　*Industrialbuildingsoftenrequiresignificantlyhigherconcentratedloads.

　　Asloadingincreases,largerbeamdimensions—ormultiplelaminatedLVLmembers—mayberequiredtomaintainstructuralsafety.

　　ApplicationType

　　Differentbuildingcomponentsperformdifferentstructuralfunctions,meaningtheyrequiredifferentLVLspecifications.

　　Typicalapplicationsinclude:

　　*Floorbeams

　　*Roofbeams

　　*Windowanddoorheaders

　　*Rimboards

　　*Columns

　　*Structuralframingmembers
