Riveted and welded connections are two common methods used in civil engineering for joining structural members together. Here's a brief overview of each:

Riveted Connections:

In riveted connections, structural members are joined together using rivets, which are cylindrical metal pins.

The process involves drilling matching holes through the pieces to be joined and then inserting the rivets through these holes.

Once inserted, the ends of the rivets are hammered or compressed to create a second head, securing the joint.

Riveted connections were widely used in the past for bridges, buildings, and other large structures.

Welded Connections:

Welded connections involve fusing the ends of two structural members together using heat and pressure.

This process creates a strong bond between the members, often stronger than the base metal itself.

Welding can be done using various techniques such as arc welding, gas welding, or laser welding.

Welded connections are commonly used in modern construction for their efficiency, strength, and versatility.

Now, here's an objective type question based on the information provided:
