Composite rectangular section

Previous pageReturn to chapter overviewNext page


Compute the shear stresses due to the vertical shear force Vy=20 KN.

We consider a composite wood beam section, see figure (dimensions [mm]).


If we take the material E1 as material of reference, we have:

n21=E2/E1=1.5 and I0=Ix1+n21*Ix2


Max tsy (glue) = max tsy (y=90)=552 kPa

Max tsy (wood E1) = max tsy (y=0)=759 kPa
