Fastener bearing load
Webcase of single shear joints, fastener rigid body rotation. The ASTM standard defines that the bearing strain (εbr) is the ratio of the deformation “δ1” of the bearing hole in the direction of the bearing load and the original diameter of the hole “D”. Fig 1 shows the procedure proposed by ASTM for double shear joints: the relative Weband large bearing exerted by the bolt (Figure 9). Other items affecting the bearing problem may be the presence of a nearby bolt or the proximity to an edge in the direction of the load. Therefore, the bolt spacing and edge distance will affect the bearing strength of a connection. Tension Shear Block Shear
