Stress values for GLB (in wood layers near neutral axis)
Stress values for GLB (in wood layers near neutral axis)
(OP)
I am trying to find out stress values (fb, fv) for those layers between top and bot. layers of a GLB. The reason is because I have this situation where the top layer (the strong one) of this cantilever GLB has to be cut (it hits the roof). This cantilever (5ft only) beam suports a point load (another beam)and now I have to check if it fails in shear and bending (because the top layer will be cut).
If I could have and idea as to how much the 2400psi and 195psi values reduce when the top layer is missing.
Beam is 8.75x48
Thanks.

On that basis you can estimate an allowable stress. When taking this approach I try to be conservative to account for notch effects and other factors.
