The riveted connections are nowadays obsolete. The understanding of this type of connections for the strength evaluation and rehabilitation for an older structure is essential. While the connection procedure for riveted connections is the same as that of the bolted connections.
A rivet is made up of round ductile steel bar which is called as ‘shank’ and with a head at the one end. It is made up of mild steel or high tensile steel.
Riveting is a particular method of connecting together pieces of metal. This process is conducted by inserting the ductile metal pins called as rivet into the holes of pieces to be joined and formed ahead at the end of the rivet to prevent each metal piece from coming out. The shank of the rivet is made up of the length to the extent through the different parts which are to be connected and with sufficient extra length for a second head to be made at the other end.
The rivets are generally classified as follows
Hot driven rivets: The rivets which are driven in the hot conditions
Shop rivets: The rivets which are placed in the workshop
Field rivets: The rivets which are placed in the site/field.
Cold driven rivets: Since high pressure is required to form the head at room temperature this type of rivet is limited.
