Framing & StructuralCâu 332 / 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
Giải thích
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.
