What is the difference between bearing-type and slip-critical bolted connections?
What will be an ideal response?
In bearing-type connections, the high-strength bolts are assumed to bear against the sides of the holes in the connected and connecting elements, whereas in slip-critical connections, the high-strength bolts are assumed to clamp the connected parts together with such pressure that the shearing force is resisted by the friction between the connected parts, and not by shear stress on the fasteners. In slip-critical connections, the connecting bolts are not considered to come in contact with the sides of the holes through which they pass. However, this type of connection must meet all requirements for bearing connections as well as provide slip resistance because it must be assumed they could eventually slip into bearing.
