What methods used to join structural members?

Structural members can be joined using various methods, including welding, bolting, and riveting. Welding involves melting the materials at their joint to create a strong bond, while bolting uses mechanical fasteners to connect members without altering their material properties. Riveting, an older method, involves deforming a metal pin to secure two or more pieces together. Each method has its own advantages and is chosen based on factors like material type, load requirements, and environmental conditions.
