LVL posts crushing plywood & plates

[BSE05]

I am designing a 4 story wood apartment building with some LVL posts with loads approaching 20K.
I have asked that all posts be on continuous LVL material, ie no interuption from plates or plywood flooring. The wall panel supplier has questioned this. Am I being unreasonable or is crushing a real concern? I am interested in the forums experience with this.

If the end bearing stress in the columns exceeds the allowable perpendicular to grain stress of the plate, crushing will occur. Then you either need to provide a bigger column, a plate with greater allowaable perpendicular to grain stresses, or a metal bearing plate.

Crushing and bearing reactions are always a problem, in wood framing, when you have to upgrade to engineered wood products.

It is a simple check and should always be done
