Shear flow in bolted box beam

To compute the bolt average shear stress and the bearing stress between the bolts and the plywood, begin with the shear flow equation:

The shear flow q will be calculated with values determined for V, Q, and I.

Using the shear flow q and the bolt spacing s, the bolt force will be computed for a 300-mm beam segment.

After the bolt force has been determined, the bolt average shear stress and the bearing stress between the bolt and the plywood webs can be determined.
