Shear loads in bolted connections are classified as either Friction Type or Bearing Type . A brief definition is as follows ... 

The tensile-shear loading was realised in a set-up involving the three specimens of the same batch as follows. The bottom leg of the top specimen was connected to the top leg of the middle specimen with a bolt with a washer of the same thickness as that of the given adhesive layer in order to assure symmetrical loading. The middle specimen was connected in a similar way to the lowest specimen (Fig. 25). 

P(5) Holes for structural connections using bolts loaded in shear shall be formed so that each bolt is a close fit in the mating holes of the parts to be joined and so that no loads due to misaligned holes are imparted to either of the FRP laminates being joined. 

A typical shear stress or strain distribution in an adhesively bonded lap joint is shown in Figure 5.38. If fasteners are placed in conventional positions (i.e. metal bolted connections), they are located in the area of minor shear stresses. Therefore, when the joint is undamaged the fasteners will be only moderately loaded. 

The most critical area of the tower design is the tower-to-foundation connection. Both shear forces and moments are at a maximum at this point. Anchor bolts are generally used at the base of steel towers. Such bolts must be proportioned to transfer overturning loads from the tower to the bolts. The bolts must be deeply embedded in the concrete footing block in order to transfer their loads to the footing reinforcement.
