Optimistic Outlook for Structural Bolts in Construction Industry

What are bolts that use bolted angle cleat connections and share bolt holes between the webs of columns and girders over more than one bay of a structure called?

a) Slip-critical bolts b) Friction grip bolts c) Bearing bolts d) Flexible bolts

Answer:

Bearing bolts are the correct term for bolts that use bolted angle cleat connections, sharing hole between webs of columns and girders over multiple bays in a structure, they are not tensioned like slip-critical bolts but instead rely on bearing against hole edges.

The term you are looking for when describing bolts that use bolted angle cleat connections and share bolt holes between the webs of columns and girders over more than one bay of a structure is known as bearing bolts. Bearing bolts allow for shear transfer between connected elements in a steel frame and are designed to bear against the hole edges. These bolts are tightened to a snug-tight condition and carry loads primarily through bearing against the hole, unlike friction grip bolts (also known as slip-critical bolts) which are pre-tensioned to develop friction between the faying surfaces.

Bearing bolts are commonly used in structural applications where slip is not a design consideration, for instance, in bracing connections where movement does not affect the serviceability or strength of the structure. With the use of bearing bolts, constructors can ensure reliable connections that meet structural requirements and contribute to the overall safety and performance of the building.
