Bolted connections are examined in detail, highlighting their preference over rivets and welds in construction due to efficiency and reliability. Various types of bolts, specifically A325 and A490, are discussed along with their properties and applications. The chapter also differentiates between bearing and slip-critical connections while detailing the nominal strength of bolts and potential failure modes.

- A325 and A490 are the most common high-strength bolts used in construction.
- The strength of a bolted connection can be affected by its design and the type of load it carries.
Key Concepts
-
Term: Bolted Connections
Definition: Joint mechanism using bolts to connect structural elements.
-
Term: High Strength Bolts
Definition: Bolts designed to withstand higher loads, primarily A325 and A490.
-
Term: SlipCritical Connection
Definition: Type of bolted connection that transmits load through friction between surfaces.
-
Term: Bearing Type Connection
Definition: Connection that transmits load through shear and bearing of the bolt.
-
Term: Nominal Strength
Definition: Calculated strength of a single fastener based on tensile properties and area.
