Friction Connection

Definition

A friction connection is a structural connection where two or more steel members are clamped together by high-strength bolts, transmitting loads between them by friction along their mating surfaces.

Purpose

The purpose of a friction connection is to provide a secure and strong joint in structural steel construction, ensuring that loads are effectively transferred without slippage between the connected members.

Examples of Use

• In high-rise building construction, friction connections are used to join steel beams and columns, providing stability and load transfer.
• Bridges often use friction connections to connect various structural elements, ensuring the integrity and safety of the structure.

Related Terms

• Bolted Connection: A method of joining steel members using bolts, which can include friction connections or shear connections.
• Welded Connection: Joining steel members by welding, providing a continuous and often stronger connection.
• Shear Connection: A type of bolted connection where the bolts resist shear forces rather than friction.

Notes

Friction connections require precise installation and tightening of bolts to ensure the necessary clamping force is achieved. They are essential for maintaining the structural integrity of steel frameworks.
