ABSTRACT
If the joint cross section is fairly constant, the value of / 8 T calculated for the joint face may be substituted into Eq. (28) to determine the bending stiffness of the clamped material. In this case, the moment of inertia for the joint face is also the equivalent moment of inertia for the clamped material, Ism (/sT = lscrs)·
/Bern= zk [fk /:)rl (29) The following equation is the generalized formula for the force ratio. Note that VDI 2230
does not explicitly account for the hole in the moment of inertia, / 8 e" for this equation. This was done in earlier revisions, however, and would appear to more consistent with the overall beam bending formulation.
