Figure 2.63 Extended Single Plate Connection With Axial Load.

2.5.3 Extended tab with axial
An alternative to the connection shown in Sec. 2.5.1 would be to use an
extended tab designed to carry the axial force as shown in Fig. 2.63.

Maximum plate thickness. The transfer of the axial force is clear. However
there are still uncertainties about the distribution of eccentricities so it
is recommended to maintain the ductility requirement relating bolt
strength to plate strength.
