23. STEEL CONNECTIONS
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.
Sections
The section covers bolted connections in steel structures, emphasizing their types and strengths compared to traditional methods like riveting and welding.
Bolted connections are favored for their efficiency and reduced labor compared to rivets.
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.
Bolted Connections
Joint mechanism using bolts to connect structural elements.
High Strength Bolts
Bolts designed to withstand higher loads, primarily A325 and A490.
Slip-Critical Connection
Type of bolted connection that transmits load through friction between surfaces.
Bearing Type Connection
Connection that transmits load through shear and bearing of the bolt.
Nominal Strength
Calculated strength of a single fastener based on tensile properties and area.
