Connection

Definition

A connection is the union or joining of two or more distinct elements. In a structure, the connection itself often becomes an entity, and the actions of the parts on each other may be visualized in terms of their action on the connection.

Purpose

The purpose of a connection is to transfer loads and forces between structural elements, ensuring stability and integrity of the overall structure. Proper connections are critical for the safety and performance of buildings, bridges, and other structures.

Examples of Use

• Steel beams are connected to columns using bolts or welds to form a rigid frame in a building.
• In timber construction, connections are made using nails, screws, or metal brackets to join wood members.
• Precast concrete elements are connected using embedded steel plates and bolts to assemble structural components on-site.

Related Terms

• Joint: A point where two or more components meet or are connected.
• Fastener: A device, such as a bolt or screw, used to hold components together.
• Moment Connection: A type of connection designed to transfer bending moments between connected members.

Notes

Connections must be designed to handle the specific types and magnitudes of forces they will encounter. This includes considerations for shear, tension, compression, and bending loads.
