Depending on its intended function, it may be a floor beam, joist, rafter, ridge beam, header, or lintel. Characteristic Properties are determined in accordance with AS/NZS 4063.2:2010 and so comply with the provisions of the New Zealand Building Code through clause 2.3 for engineering design in accordance with NZS3603:1993 Timber . But the upside is that 2 workers can usually handle the weight of each lamination as it is assembled. The span is based on a load-bearing capacity of 1,360 pounds per square foot and a deflection limit of L/360. If you size a roof beam like a structural ridge that has a L/240 limitation, you would multiply the minimum E-value by 0.666 (785,000 x 0.666 = 522,810 in this case). The width can be increased by laminating in multiples of 1-3/4 inches or 40mm.
