Eccentricity Normal to the Plane of the Faying Surface

Eccentricity Normal to the Plane of the Faying Surface

RE: Eccentricity Normal to the Plane of the Faying Surface

Here are my study slides for bracket bolts. Rut is usually the tensile force imposed on a single bolt in the worst cased scenario. Just make sure your algebra works out for however many columns of bolts you have. Case 2 gets presented in a few different ways throughout the literature.

RE: Eccentricity Normal to the Plane of the Faying Surface

rut is the force in an individual bolt. The graphic is showing 2rut since there are two bolts at that height.

Equation 7-14 is actually pretty straight forward. The force for all of the bolt above the neutral axis is n'*rut and the force for all of the bolts below the neutral axis is n'*rut. These forces create a couple with a moment of n'*rut*dm which must equal the applied moment of Pu*e.

n' = number of bolts above the neutral axis
rut = force in each bolt
dm = moment arm between resultant tensile force and resultant compressive force

n'*rut*dm = Pu*e
rut = Pu*e / (n'*dm)

Do you have other study slides that you would care to share? ponder

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Do you feel any better?
