V __ t r r/� Boise Cascade 1) Engineered Wood Products Ka Technical Note Inverted Installation of BOISE GLULAM® Beams in Simple Span Applications BOISE GLULAM 24F-V4, 20F-V12, 20F-V14, and 22F-V14 grade beams are manufactured with an unbalanced layup, meaning that higher strength laminations are installed in the bottom of the beam. In simple span applications, the bottom edge of the beam is in tension. Unfortunately, unbalanced glulams are sometimes installed inverted (the 'TOP"stamp is visible when looking up at the beam from below). The glulam's load-carrying capacity is reduced when installed in this manner. qgt s d " , � A � 1 1 eta^ ' � `;�� " s Pp�� e''`ni ta ;y tfix Y �k� �,�Y '„u', , "hd . � a' $ a :'- � �'✓.€t ,` '� When installed upside down, only the bending design value of unbalanced glulam grades is actually affected. Reduction factors for Boise Glulam unbalanced grades are shown in Table 1. For example, the allowable bending value of a 24F-V4 beam is 1850 psi when inverted, compared to 2400 psi when installed properly. Thus the reduction in bending is approximately 23%. Table 1: Boise Glulam Bending Stress Reduction Factor for Inverted Installations Grade & Bending Stress Inverted Bending Reduction Species [lb/in2] Stress [Ib/in2] Factor 24F-V4 DF 2400 1850 0.77 20F-V12 AYC 2000 1400 0.70 20F-V14 POC 2000 1450 0.725 22F-V14 POC 2200 1650 0.75 If the beam is uniformly loaded simple span application, there is a simple method of determining the reduced load capacity of the inverted beam. Simply multiply the allowable PLF load (found in the BOISE GLULAM Specifier's Guide) by the reduction factor shown above for the beam application. This reduced value is the allowable PLF load for the non- cambered, uniformly loaded, and inverted beam. For non-cambered beams with non-uniform loads, the beam design may be analyzed with the BC Calc sizing software. To properly account for the reverse installation, the allowable Tech Note GB-2 Page 1 of 2 rev. 11/2013(valid 2 years past publish date) a R&B Engineering, LLC JOB ' 3r 9127 SW Fir Grove Lane SHEET NO.
