Effect of Large Diameter Horizontal Holes on the Bending and Shear Properties of Laminated Veneer Lumber (LVL)
Technical Note
Laminated veneer lumber (LVL) products are often specified where a certain span, strength and/or stiffness is required. As such, they are generally designed for and used in applications where they will be highly stressed under design loads. For this reason, field modifications such as notching, tapering or drilling that are not shown on the design or shop drawings should be avoided.
This publication is designed for: builders, contractors, engineers, designers
APA Technical Note G535 provides prescriptive guidance for notching and drilling on LVL when the end notching and drilling of horizontal through-thickness holes cannot be avoided. However, in the structural design phase or in the field, some horizontal holes exceeding the guidance provided in G535 may become a necessity.
This publication provides an analytical tool for those conditions through engineering equations and supplement hole placement requirements.
Key sections include:
Limitations
Effect of horizontal holes on the bending capacity
Effect of horizontal holes on the bending stiffness
