Present values must only be used for bending of panels in the major strength axis. 5) Spans shown represent distance between the center lines of supports and are to be used for preliminary design only. 6) Span table above includes panel self weight, plus 15 psf miscellaneous dead load. (Ref: International Building Code 2012 - art. 1607.5) 7) Engineer to ensure that L/240 deflection limit is appropriate for intended use. 8) Total length is limited to max. production length (max. length for standard 40‘ container shipping is limited to 39‘) 9) The highlighted values show the decisive case (only vibration and deflection, no consideration of bending and shear stresses). 10) Deflection L/240 is considerd for snow load; L/180 is total load deflection limit. 11) For applications with deflection limits or loading different than what is indicated above, contact your binderholz technical representative.
