Framing & StructuralQuestion 332 of 700
For laminated veneer lumber (LVL) and glued-laminated (glulam) beams, where must any holes or notches be located and sized?
a.Only as permitted by the manufacturer or design professional
b.Anywhere in the middle third
c.Only within 6 inches of a support
d.Holes are unlimited because the beam is engineered
Explanation
Because LVL and glulam are engineered products, holes and notches are allowed only where and as the manufacturer's literature or a design professional specifically permits, since unauthorized cuts can sharply reduce capacity. Blanket middle-third or near-support rules, or unlimited holes, do not apply.
